Description

Technical Field

[0001] The utility model relates to the technical field of laser field mirrors, in particular to a multi-piece laser field mirror. Background Art

[0002] The field lens refers to a lens that works near the focal plane of the objective lens and can effectively reduce the size of the detector. To be precise, the field lens should work in the image plane of the objective lens. On the one hand: the object plane of the field lens coincides with the principal plane. From the characteristics of the principal plane, it can be seen that its magnification is 1, so it does not contribute to the magnification of the system; on the other hand, the field lens should project the aperture surface of the objective lens onto the entrance pupil of the eyepiece. For a single lens, the aperture surface is also the exit pupil. This ensures that the output light of the objective lens can pass through the eyepiece to the maximum extent. When using a laser field lens, the laser field lens is installed by using a threaded connection. However, during the installation process, the threaded connection method is prone to excessive or insufficient force, resulting in excessive or insufficient installation of the field lens, resulting in an unstable installation. During use, the field lens is prone to fall, affecting the use of the field lens. For this reason, we propose a multi-piece laser field lens. Utility Model Content

One side of the connecting plate 7 is fixedly connected with a pushing guide block 8 with a vertical triangular cross-section.
