Abstract
The utility model discloses an optical configuration applied to an optical measuring instrument which realizes a wave length be chosen by making use of a filter wheel. The utility model comprises a support base, a collective lens and the filter wheel which is provided with a filter; the collective lens is fixedly arranged on the support base and the filter wheel is arranged on a supporting axle and can be rotated; an axial line of the collective lens is positioned below the axial line of the supporting axle; As the axial line of the collective lens is positioned below that of the supporting axle, the height of an optical axle of a horizontal light path can be reduced, as a result, the position where an optical fiber outlet of a luminiferous beam of rays may also become lower, and therefore the space occupied by an entire optical system may also be narrowed, thereby making the thickness of the entire machine thinner.
Description
Technical field
The utility model relates to the optical gauge field, especially takes turns the optical gauge of selecting wavelength about a kind of rotating filtering sheet that utilizes.
Background technology
In the prior art, it is a variety of to utilize rotatable optical filter wheel to select the optical gauge of wavelength to have, as microplate reader, biochemical instruments, spectrophotometer etc.See also Fig. 1 to Fig. 3, for microplate reader, its optical texture generally comprises illuminator 1, collector lens 2, optical filter wheel 3, optical filter 4 and optical fiber and passes light beam, the filament of this illuminator 1 is centered close on the axis of this collector lens 2, the axis 5 of this collector lens 2 has promptly been determined the horizontal optical path optical axis 5 of this optical texture, this optical filter 4 has a plurality of and embedding is fixed on this optical filter wheel 3, this optical filter wheel 3 is rotatable, this horizontal optical path optical axis 5 is positioned on the rotary motion trace of this optical filter 4, and the axis that this optical fiber passes the optical fiber inlet 6 of light beam overlaps with this horizontal optical path optical axis 5.This collector lens 2 and optical filter wheel 3 are installed on the bearing 8, this collector lens 2 embeds and is fixed in this bearing 8, this optical filter wheel 3 is by bolster 82 rotatable being installed on this bearing 8, this collector lens 2 is positioned at the side of this optical filter wheel 3, and the axis 5 of this collector lens 2 is contour with the axis 821 of this bolster 82.But, there is following shortcoming in this kind optical texture: optical filter wheel is that a diameter is than the moving link that needs in big and the work to rotate, in order to guarantee the rotation of optical filter wheel, the shaft core position (being the axial location of bolster) that needs to guarantee optical filter wheel is arranged enough high, its maximum wheel rim does not touch machine bed plate when making the optical filter wheel rotation, again, the axis 5 of collector lens is contour with the axis 821 of bolster, the height that causes the horizontal optical path optical axis is also than higher, because the optical fiber of microplate reader passes the optical fiber outlet 7 of light beam and structurally requires to be higher than one section height of horizontal optical path optical axis, so than under the condition with higher, the height of optical fiber outlet is had to higher and is finally caused the machine thickening in the position of horizontal optical path optical axis.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the deficiencies in the prior art, provides a kind of and can reduce complete machine thickness, makes the compact more optical filter wheel that utilizes of complete machine select the optical texture of the optical gauge of wavelength.
The technical solution adopted for the present invention to solve the technical problems is: this utilizes optical filter wheel to select the optical texture of the optical gauge of wavelength, comprise bearing, collector lens and the optical filter wheel of optical filter is installed, this collector lens is fixedly mounted on this bearing, this optical filter wheel is installed on the bolster and turns, and this is characterized in that: the axis of this collector lens is positioned at the below of the axis of this bolster.
The axis of described collector lens and the parallel axes of this bolster.
The axis of described collector lens is positioned on the vertical guide at axis place of this bolster.
The invention has the beneficial effects as follows, because the axis of collector lens is positioned at bolster axis below, then the height of horizontal optical path optical axis reduces, thereby but light passes the also step-down of position of the optical fiber outlet of light beam, but the shared space of whole optical system is step-down also, make the thickness of complete machine can be thinner, make complete machine compact more.

Embodiment
See also Fig. 4 to Fig. 6, the utility model utilizes optical filter wheel to select the optical texture of the optical gauge of wavelength to apply on the microplate reader, it comprises bearing 8, collector lens 2 and optical filter wheel 3, this bearing 8 is provided with the installation cavity 81 that runs through, this collector lens 2 embeds and is fixed in this installation cavity 81, this optical filter wheel 3 is installed in bolster 82 and can rotates around this bolster 82, this bolster 82 is fixed on the bearing 8 by screw 83, and a plurality of optical filters 4 are installed on this optical filter wheel 3, and this optical filter 4 evenly distributes with circumference.This collector lens 2 is positioned at a side of this optical filter wheel 3, the axis of this collector lens 2 is positioned at the below of the axis of this bolster 82, and the axis of this collector lens 2 is positioned on the rotary motion trace of this optical filter, preferably, the parallel axes of the axis of this collector lens and this bolster and being positioned on the vertical guide at axis place of this back shaft.
Because the axis of collector lens is positioned at the axis below of bolster, the position of horizontal optical path optical axis is lowered, therefore optical fiber pass light beam the optical fiber outlet the position thereupon step-down some, taking up room that optical system is total just can design lowlyer, thereby can make the complete machine thinner thickness.According to the microplate reader that this structural design goes out, not only complete machine attenuation, and also the complexity of physical construction does not increase and makes moderate progress, assembling capacity and maintainable good.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
