In the various figures, like parts are designated by identical references.

Referring to Figures 1 and 2 describes a fastening system 10 of an optical element

12.

The optical member 12 is for example a filter, a grism, a prism, an array or a lens. In the following description, and unless otherwise stated, the optical member is of cylindrical shape with circular base, such as a filter or a lens.

The optical member 12 comprises two main surfaces, each adapted to transmit light radiation and a peripheral edge portion 13 of the optical member.

The fastening system 10 comprises a support 14 and at least one fastening device 16 of this optical member 12 to the support 14.

One optical element is shown in Figure 1 to simplify the description of the system. Of course, multiple optical members can be simultaneously fixed by the fixing system by means of one or more fastening device 16, as will be described in more detail below.

The support 14 is intended for example to be placed in a cryogenic device.

It includes a cavity 18 and at least three fixing studs 20, each located outside the cavity.

For example, the support 14 is of a material comprising aluminum, in particular aluminum.

The fastening device 16 is adapted to be mounted on the support 14 for receiving the optical members 12. For this purpose, the support 14 comprises at least three fixing studs 20 and the fastening device 16 includes at least three fasteners for permit engagement with the fastening pads 20 of the support 14 which are each intended to receive one of the fixing members of the fixing device 16.

Each fastener pad 20 is for example an embossed cylinder with respect to the support surface. In this case, the cylinder is in the lumen of the support. Of course, the attachment pads may have other forms.

Preferably, the carrier 14 comprises only three mounting pads 20 and the fixing device 16 includes three fasteners to allow engagement with the three studs 20 for fixing.

The fastening device will now be described in more detail with reference to Figures 3 and 4 illustrating a first embodiment in perspective and face.

The fixing device comprises a flange 24 having an inner face 26 intended to be positioned facing each optical member 12 to be fixed.

The flange 24 is made of elastically deformable material. Preferably, the flange 24 is of a material having a higher thermal expansion coefficient than or equal to 5.10 "6 K" 1 and having a Young's modulus at least greater than or equal to 70 MPa. In addition, the flange 24 is of a material having a limit of elasticity greater than or equal to 400 MPa. These values ​​make it possible to ensure good retention of the fastener 16 on the support 14 while having both a good thermal accommodation taking into account the differential expansions of the materials and good mechanical strength.

For example, and advantageously, the flange 24 is made of metal material mainly comprising titanium, particularly titanium.

In addition, the flange 24 is substantially circular, elliptical or triangular. Preferably, the flange 24 is substantially circular in shape.

It comprises at least three open loops 28 of each material constituting a fixing member. Each open loop 28 is connected with material continuity by the segments 30 so that the flange material is formed of a single piece.

The open loops 28 forming the fixing members are distributed at equal angular intervals. Thus, for example if the flange 24 only has three open loops, they will be angularly spaced by 120 °.

Moreover, they are each formed an arc subtending an angle of between 180 ° and

320 °. The flange 24 is for example manufactured by a method comprising at least a step of cutting by electroerosion to son according to the invention thus allowing the flange is formed in one piece. Such a manufacturing process provides a highly accurate and inexpensive room.

The fastening device 16 comprises at least three strips 32 each consisting of an elastically deformable material and comprising first and second ends.

Each strip 32 is connected in continuity of material with the flange 24 at its first end 34 to the inner face 26 of the flange. Of course, in other embodiments, each blade 32 may be fixed for example by welding at its first end 34 to the inner face 26 of the flange 24.

The second ends 36 of each strip 32 are intended to maintain contact each optical member 12 to be fixed. To this end, the second ends 36 are supported on a portion of the peripheral portion 13 of the optical member 12.

The slats 32 are distributed at equal angular intervals. They are directed towards the geometric center of the flange 24. The major face of the strips 32 forms an angle β with the noted plane tangent to the flange 24 at the connection point between the first end 34 and the inner face 26 of the flange.

Preferably, there are as many as 32 open loops strips 28, allowing respectively associating each lamella 32 in an open loop 28.

The angular difference, denoted a in Figure 4, between the first end 34 of a slat 32 and the center of an open loop 28 is substantially between 10 ° and 60 °.

Each open loop 28 constituting the fastening members is adapted to open or close by elastic deformation to open or close the angles β in Figure 4, between the second ends 36 of the flexible blades 32 and the inner face 26 of the flange 24.

Such an embodiment allows each slat to ensure isostatic holding the optical member without damaging deformation during high e.g. temperature variations during a cooling phase. Advantageously, it guarantees the maintenance of the optical member without the use of glue and a minimum vignetting on the optical member.

In particular, in the case where the optical member 12 includes a 38 partially or completely circumferential groove forming part of the peripheral portion 13 of the optical member, each strip 32 may be adapted so that its second end 36 is inserted into the circumferential groove 38 of the optical member 12, as illustrated in figures 2 and 4. the groove 38 is shown in dashed lines in Figure 4.

Such an embodiment, wherein each slat is inserted in the circumferential groove of the optical member to be fixed is particularly advantageous because it ensures a very good lateral holding the optical member without the use of glue and a minimum vignetting on the optical member 12.

A second embodiment of the fastening device 56 is illustrated in Figures 5 and 6. The attachment device 56 is identical to that described in the first embodiment except for the second end 66 of the slats 52.

Indeed, according to this second embodiment, each strip 52 comprises at its second end 66 in contact with the optical member 12 a lateral holding means 68 of the optical member 12. The lateral support means 68 is shaped U.

The fixing device according to this second embodiment is particularly suitable for optical members devoid of circumferential groove.

Such an embodiment, wherein each lamella ends U-shape is particularly advantageous as it ensures a lateral support of the optical member from the outside thereof also without the use of glue.

Whatever the embodiment, such a fixing device according to the invention inserted at the interface between the support and the optical member makes it possible to ensure a maintenance of the optical member by elastic deformation.

In fact, the fixing device behaves like a clamp around the optical member 12. During high temperature fluctuations, for example of the order of 200 K, the expansions are absorbed by the elastic deformation of the slats playing as springs. The optical member sees about ten times less effort to support the second ends of the slats than the force applied to each of the open loop constituting the attachment members (radial loads). Thermal flexibility and mechanical strength are obtained in particular by using a material containing titanium.

Such systems for fixing at least one optical element are such as applications in devices subjected to high temperature variations, especially in cryogenic devices comprising at least one fixing system according to the invention. According to the invention, the optical system may comprise a plurality of fasteners for securing a plurality of optical members.

For example, Figure 7 illustrates a fastening system 70 for securing together two lenses 72A, 72B having a support 74 and two fastening devices as described above.

The two holding devices 16A, 16B are shown fastening devices according to the first embodiment and the optical members 72A, 72B are each provided with a circumferential groove 38. Of course, the fastening system 70 may include attachment devices according to the first or second embodiment and the optical members to be fixed by the device are provided or not with a circumferential groove and whatever the embodiment the fastening device selected.

In the example illustrated in Figure 7, the two fastening devices 16A, 16B are fixed on either side of the support 74. Of course, two securing devices 16A, 16B may be attached on the same side of the support 74 according to other embodiments.

The fastening pads 20 of the carrier 74 are intended to receive both the fixing members of the first and second optical devices 16A, 16B. Of course, in other embodiments the support 74 may comprise a first group of at least three mounting pads 20 for receiving the fastening elements of one of fasteners 16A and a second group of at least three mounting pads 20 for receiving the fastening elements of the other of fasteners 16B. The two mounting pad groups 20 can then be angularly offset or non.La 8 illustrates another example of fastening system 80 for securing together two prisms 82A, 82B having a support 84 and two fastening devices as described above -above.

The support 84 comprises at least one group of at least three bonding pads (not visible in this figure) for receiving the fasteners or the fasteners 16A, 16B.

The two holding devices 16A, 16B are shown fastening devices according to the first embodiment and the optical members 82A, 82B are each provided with a circumferential groove 38. Of course, the fastening system 80 may include attachment devices according to the first or second embodiment and the optical members to be fixed by the device are provided or not with a circumferential groove and whatever the embodiment the fastening device selected. Such an embodiment of a fixing device makes it possible that the expert called optical stacks organs guaranteeing a highly accurate optical centering isostatic organs.

9 illustrates another embodiment of a fastening system 90, adapted to simultaneously securing a plurality of optical members 92 having a support 94 and a plurality of fasteners 56.

The support 94 has a plurality of cavities and at least as many groups of at least three mounting pads 20.

The cavities are preferably arranged minimizing the space between two cavities. For example, the cavities are distributed at equal angular intervals and equidistant from the geometric center of the support 94.

Each group of at least three mounting pads 20 is disposed at the periphery of a recess and each stud fastener of the same group is intended to receive a fixing member of a fixing device placed opposite said cavity.

clip 56 illustrated devices are fastening devices according to the second embodiment. Of course, the fastening system 90 may include attachment devices according to the first or second embodiment and the optical members to be fixed by the device can be provided or not with a circumferential groove and regardless of the mode of embodiment of the fastening device selected.

The fastening devices 56 are arranged in the same plane, each facing a cavity.

Such an embodiment is useful for producing, for example the wheels of optical filters. This is possible thanks to the compactness of fixing devices according to the invention. A fixing method according to the invention at least one optical member 12 of a support 14 by means of a fixing device as described above will now be detailed.

This fixing method has a flange the opening step 24 of the fixing device by simultaneous elastic deformation of at least three open loops 28 by a radial spacing means. This radial spacing means is for example a micrometer for obtaining a measured spacing open loops. Next, the optical member 12 is installed within the open flange 24. The optical member 12 is then held laterally within the flange 24 closing the flange 24 by elastic deformation reverse open loops 28 simultaneously.

According to one embodiment, once the flange mounted around the optical member, the flexible strips being trapped in the circumferential groove of the optical member if the latter is provided, the whole forms an integral assembly as illustrated in Figure 4.

According to another embodiment, in the case of an unmachined optical member, that is to say devoid of circumferential groove, the resilient bands retain the captive optical member from the outside this time and any also form an integral assembly as illustrated in Figure 6.

In addition, it is possible to set in rotation the optical member along its axis of revolution, for example a network, the optical member is not bonded to the fastening device.

The fixing device of the optical member 12 is then fixed to the support 14 using the open loops 28 of the fixing device. For this, the open loops 28 are again opened by a radial spacer means for engaging each around one of the support fixing studs. This angular opening is formed with a smaller amplitude than in the flange opening step 24 in order to ensure a minimum holding the optical member 12 in the fixing device.

The open loops 28 each constituting a fixing member so engaged around fixing the support pads help to ensure a holding position of the fastening device of the optical member on the support.

The clamping force on the flexible blades is decoupled by about a factor 10 relative to the mounting force of the fasteners on the support fixing studs. With such a stress ratio, the invention ensures a clamping dispersion of about ± 10% for 80 K temperature and pairs of materials such as glass, silica for the optical member, aluminum and titanium for the support to the flange of the fastening device.

For optical bodies of a few grams and keeping efforts of several hundred grams, it has been shown by the inventors that the invention ensures continued friction position that largely resists 10 billion in quasi-static.

Such fixing device may be implemented in any optical instrument subjected to high temperature variations, in particular any optical instrument used in the infrared at 80 K such as cameras, telescopes ... A fixing device according to the invention keeps firmly and precisely without bonding the optical member and in particular without deformation in a cryogenic environment. The invention also has the advantage of providing a very accurate isostatic centering and allows a stack of optical members on the mounting bracket pads.

In addition, the absence of bonding allows rotational adjustment of the optical member along its axis of revolution, which is very useful for adjusting for example, optical networks or prisms.

In addition, its high compactness allows to insert in a small space and involve several in a multiple optical members fastening system.

Of course, the present invention is not limited to the examples and described and illustrated embodiments, but is capable of many variants accessible to the skilled person. For example, those skilled in the art will adapt the number and position of the open loops and lamellae in order to use a fastening device according to the invention for fixing optical members substantially rectangular or square in order to preserve the advantages described below -before.
