Definitions

  • the invention relates to a holder for optical elements, according to the preamble of patent claim 1.
  • Such frames serve for the precise mechanical mounting of optical elements, for example the lenses of a lens, in precisely defined positions within an optical system, and also in several ways: for example, the frame holds the lenses of an object at a certain distance from one another, furthermore in the correct radial position, in which the lens center coincides with the optical axis of the system, and in the correct inclination of the lens plane perpendicular to the optical axis of the system.
  • the frame holds the lenses of an object at a certain distance from one another, furthermore in the correct radial position, in which the lens center coincides with the optical axis of the system, and in the correct inclination of the lens plane perpendicular to the optical axis of the system.
  • slight deviations of a lens with respect to one of these three main criteria result in undesirable system errors.
  • a fine correction of the lens adjustment takes place, in which individual lenses, in particular those which critically influence the system, are corrected with regard to their relative position.
  • the overall error of a lens system can be optimally corrected taking into account all manufacturing tolerances of the individual lenses and the mechanical components involved.
  • Correct lens inclination i.e. the position of the lens plane perpendicular to the optical axis of the system, is particularly important when correcting when a high-performance lens is assembled.
  • the centering of the lens body with respect to the optical axis also has a considerable influence on the accuracy of the system.
  • the lenses of precision objects are inserted or fitted into very precisely manufactured frames.
  • the spacing of the individual lenses is guaranteed by fixed or adjustable intermediate rings.
  • auxiliary frames for the individual lenses are also known, in which the lenses are embedded using mechanical means, by gluing or other adhesives.
  • Word directions are also known in order to compensate for the influences of the different materials, for example with regard to their coefficient of expansion, without the lens bodies being damaged or the optical properties of the system being changed inadmissibly.
  • the desired distances between the individual elements are set, for example, by appropriate design of the auxiliary frames or by non-realizable spacer elements. Examples of lens systems which are constructed according to the last-mentioned principle are known from DE-OS 15 72 729.
  • GB-PS 1 528 084 a resilient mounting of individual lenses in the axial direction is known.
  • the lenses are pressed without play against a support in the frame body, a spring ring acting on the opposite side of the support, viewed in the axial direction, preferably at individual points on the lens surface and thus pressing the lens body against the support.
  • a frame with a spring ring is known from FR-OL 2 428 852, which acts on the periphery of the lens body and is intended to center the lens body axially with respect to the frame body. This is intended to compensate for an axis replacement between the optical axis of the lens and the mechanical system axis.
  • This suggestion is not sufficient for reproducible fine-tuning of system errors that arise due to manufacturing-related tolerances of the individual lenses, especially with the high accuracy requirements mentioned above.
  • none of the previously suggested solutions for fine adjustment of individual elements of an optical system with respect to the criteria mentioned at the outset is sufficient, as is required, for example, for the lenses of high-performance objects.
  • This measure makes it possible to align individual optical elements particularly simply and reliably, and the adjustment can be carried out from the outside when the system is assembled. This considerably simplifies the adjustment, in particular of high-performance lenses, and increases the reliability for optimal adjustment.
  • Fig. 4 is a partial view of the adjustment device for the embodiment of FIGS. 3A and 3B.
  • 5A and 5B section and top view for an adjusting device of an auxiliary frame in a main frame.
  • the invention described in more detail below with reference to the examples essentially provides an auxiliary version, which in turn is inserted into a main version.
  • the auxiliary frame has adjustment devices for adjustment in three degrees of freedom.
  • it is provided with adjusting elements for the angular orientation of the mounted optical element and for the individually adjustable mutual spacing along the optical axis.
  • auxiliary frame Preferably there are second adjustment means between the auxiliary frame and the main frame, so that the auxiliary frame with the optical element relative to the main frame in the three remaining degrees of freedom, in particular in a plane perpendicular to the optical axis, for example in the X and Y directions, can be adjusted with the optical system axis as the Z axis.
  • a lens 1 is held in an auxiliary frame 2.
  • three eccentric adjusting devices 4A, 4B and 4C are provided on the outer periphery of the auxiliary frame 2.
  • the eccentric of this adjusting device rests on a base 3, which is represented in the preferred example by the main version described in more detail later.
  • a compression spring 5 in the area of each of the eccentric adjustment devices 4 provides a counter pressure on the auxiliary frame 2, whereby the adjustment device is pressed against the base 3 without play.
  • the eccentric of the adjusting device is in the form of an Archimedean spiral.
  • the adjusting device 4 is provided with a slot 6, so that the adjusting device 4 can be secured from the outside with a suitable tool, e.g. with a screwdriver.
  • the lens plane can be adjusted at right angles to the optical axis Z of the system.
  • the distance to the next element of the system can be regulated.
  • the common adjustment can be carried out, for example, by an auxiliary device (not shown in more detail) which simultaneously engages in the slots 6 of the three adjusting devices 4A, 4B, 4C and carries out a coordinated adjustment.
  • FIGS. 3A, 3B and 4 show a further exemplary embodiment, in which the adjustment devices are designed as balls 11, which are located in ball sockets 12 and 13 on the auxiliary frame 2 and on the base 3, respectively. 4, the ball socket 12 can be attached directly to the auxiliary frame 2 with the aid of a cage 14.
  • balls with different diameters can be inserted into the individual pans, which allows the angular position of the lens plane with respect to the optical axis Z to be set, or all balls can be replaced by new balls whose diameter is the same amount as the old ones Different ball diameters in order to set the distance to a neighboring element to the desired value. If it proves to be expedient in the individual case, the diameter of the balls can remain constant and instead the ball sockets 12 and 13 can be changed by appropriate grinding or by widening central bores 15, 16. Instead of balls and pans, any other pairs of shaped elements with similar properties can also be used.
  • the auxiliary mount 22 shown in dash-dot lines in FIG. 5A can be adjusted in a main mount 23 in a plane perpendicular to the optical axis Z.
  • second adjustment devices 24A and 24B are provided on the main frame, which are supplemented by diametrically opposite compression springs 25, 26, so that the auxiliary frame 22 is pressed against the second adjustment devices 24A, 24B under the influence of the compression springs 25, 25.
  • the second adjusting devices 24A, 24B can in turn be designed as eccentrics, preferably in the form of Archimedean spirals. Via a slot 27, the eccentrics can be externally, e.g. with the help of a screwdriver. As indicated in FIG. 5B, this results in an adjustment possibility via the second adjustment device 24A in the X direction and via 24B in the Y direction.
  • the auxiliary frame can be rotated around the optical axis Z within the main frame.
  • the contact points between the adjustment devices and the parts to be manufactured are of perfect kinematic design. For example, they are designed as sliding surfaces on two cylinder surfaces which are rotated 90 degrees relative to one another and which only touch at exactly one point.
  • the combination ball / socket allows a play-free contact between the adjustment devices and the parts to be adjusted and, preferably in connection with the counter-pressure elements, an exact position, even when subjected to shock and vibration.
