Description
Technical field
The utility model belongs to the parts technical field of optical instrumentation, is specifically related to tunable optical and blocks.
Background technology
When people use the camera photo, often need to regulate logical light quantity, the depth of field, use always and block to circular variable light.In optical instrument, it is requisite parts that guarantee image quality that light blocks, and it is in the majority to adopt circular light to block usually, has adopted the slit tunable optical to block in some special camera chains.
It is the vitals of regulating the light district that tunable optical is blocked, and has obtained extensively promoting the use of in image optical instrument, photo-optics instrument.In some instrument, tunable optical is blocked can only be unidirectional adjustable, for example the image optical instrument of several companies in Beijing production and the tunable optical in the photo-optics instrument are blocked, its primary structure is to adopt two parallel blocks, form slit between the parallel block, the major parameter of slit is: stitch wide 0～14mm, stitch long 80mm.Its seam is wide to be to be that benchmark is adjusted with a parallel block, and variation has taken place at adjusted slit center, and it is having in the directional light experimental system of dead center, can cause that the light district is inhomogeneous up and down, can not satisfy the needs of experiment.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the shortcoming of the said equipment, provides a kind of slit center symmetry, evenly high, simple in structure, the easy to operate tunable optical of adjustable, precision is blocked.
Solving the problems of the technologies described above the technical scheme that is adopted is: the outside is set in light blocks seat the voussoir that light blocks chip module is installed, block at light and to establish its end on the seat and be arranged on light and block hold-down mechanism on the chip module, side outside light blocks seat is provided with left micropositioning stage, opposite side that left trimming hand wheel is installed and is provided with the right micropositioning stage that right trimming hand wheel is installed, the end of left side trimming hand wheel is arranged on the left end of voussoir, and the end of right trimming hand wheel is arranged on the right-hand member of voussoir.
Hold-down mechanism of the present utility model comprises screw and spring, and screw is arranged on light and blocks on the seat, and an end that is sleeved on the outer spring of screw is arranged on inwall, the other end that light blocks seat and is arranged on light and blocks on the chip module.
The utlity model has slit center symmetry, evenly adjustable, precision is high, advantage such as simple in structure, easy to operate, can in the optical device of regulating the light district, promote the use of.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but the utility model is not limited to these embodiment.
In Fig. 1, the tunable optical of present embodiment is blocked and is blocked seat 3, screw 4, spring 5, voussoir 6, light by left trimming hand wheel 1, left micropositioning stage 2, light and block chip module 7, right micropositioning stage 8, right trimming hand wheel 9 and connect and constitute.Center in light blocks seat 3. is equipped with voussoir 6, and voussoir 6 is the flat boards that symmetrical degree of tilt is arranged, and the outside of voussoir 6 is equipped with two blocks of light and blocks chip module 7, and voussoir 6 drives two blocks of light and blocks chip module 7 formation slits.Block seat at light and screw 4 is installed on 3, spring 5 is sleeved on outside the screw 4, one end of spring 5 is pressed in light and blocks seat 3 inwall, the other end and be pressed in light and block on the chip module 7, and screw 4 and spring 5 constitute the hold-down mechanism of present embodiments, and screw 4 and spring 5 are used for that two blocks of light are blocked chip module 7 and are pressed on voussoir 6.In left side that light blocks the center line of seat outside 3 with the screw threads for fastening connector left micropositioning stage 2 that has been fixedly connected, the right side is with the screw threads for fastening connector right micropositioning stage 8 that has been fixedly connected, left trimming hand wheel 1 is installed on left micropositioning stage 2, on the right micropositioning stage 8 right trimming hand wheel 9 is installed, the end of left side trimming hand wheel 1 withstands on the left end of voussoir 6, the end of right trimming hand wheel 9 withstands on the right-hand member of voussoir 6, on left trimming hand wheel 1 and right trimming hand wheel 9, be manufactured with groove, per 10 ° of angles are carved a line, the dextrorotation trimming hand wheel 1 that turns left, and the right trimming hand wheel 9 of inhour rotation, voussoir 6 moves right, driving two blocks of light blocks chip module 7 and vertically moves inward perpendicular to centerline direction, two blocks of light block chip module 7 formation slits and diminish, the left trimming hand wheel 1 of inhour rotation, and the dextrorotation trimming hand wheel 9 that turns right, voussoir 6 is moved to the left, drive two blocks of light and block chip module 7 vertical outside moving, two blocks of light block chip module 7 and form the slit change greatly, moving repeatedly continuously of voussoir 6 makes two blocks of light block the slit that chip module 7 produces continuous variable.
