Design method of a rotating shaft optical adjustment mount

Abstract

The invention discloses a design method of a rotating shaft type optical adjustment frame. The rotation axis of the optical lens fixed by the adjustment frame forms a certain angle with the normal line of the optical mirror surface. When the fixed lens unit rotates, the normal line of the mirror surface also rotates. The structure realizes double-layer rotation, and can adjust the mirror normal to any position of a certain spatial solid angle, realizing an effective two-dimensional light adjustment method.

Description

technical field [0001] The invention relates to the principle design of the optical adjustment frame. The rotation axis of the optical lens fixed by the adjustment frame forms a certain angle with the normal line of the optical mirror surface. , the mirror normal can be adjusted to any position of a certain spatial solid angle, and an effective two-dimensional light adjustment method can be realized. Background technique [0002] The adjustment of the plane mirror is very important in the optical path. At present, two-dimensional adjustments (angle pitch and yaw directions) of optical components are generally carried out in two ways: non-coplanar adjustment and coplanar adjustment. Although the two adjustment methods can better adjust the angle, pitch and yaw direction, but because the adjustment knobs of some existing optical adjustment mounts are on the side, when it is required to build a relatively compact optical path, it will make subsequent optical path adjustments d...

Problems solved by technology

Although the two adjustment methods can better adjust the angle, pitch and yaw direction, but because the adjustment knobs of some existing optical adjustment mounts are on the side, when it is required to build a relatively compact optical path, it will make subsequent optical path adjustments difficult. bring some difficulties

At the same time, for the non-coplanar optical adjustment mount, there is also the problem that the center position of the optical element (mirror surface) changes when the optical adjustment mount is adjusted

Moreover, most of today's optical adjustment mounts are composed of a movable plate (connecting the optical elements), a fixed plate, a steel ball (for supporting), a screw (for adjusting the movable plate relative to the fixed plate), and a spring (for stretching) The optical adjustment mount with this structure has poor shock resistance and is limited to fine-tuning the angle
