Description

Technical Field

[0001] The utility model relates to the technical field of lens protection, in particular to a lens protection structure for optical instruments. Background Art

[0002] Optical instruments are composed of a single or multiple optical devices. Optical instruments are mainly divided into two categories: one is optical instruments that form real images, such as slide projectors, cameras, etc.; the other is optical instruments that form virtual images, such as telescopes, microscopes, magnifying glasses, etc. A lens is an optical element made of transparent materials (such as glass, crystal, etc.). Convex lens: thick in the middle and thin at the edges, there are three types: biconvex, plano-convex, and concave-convex; concave lens: thin in the middle and thick at the edges, there are three types: biconcave, plano-concave, and convex-concave. Lenses play an important role in astronomy, military, transportation, medicine, art and other fields.

[0003] The existing optical instrument lenses lack a protective structure, so that the lenses are exposed when not in use, which is easy to be contaminated with dust and affects the use. When the staff accidentally knocks over the optical instrument, the lenses may be scratched or damaged, thereby causing certain economic losses and being inconvenient for people to use. Therefore, the utility model provides a lens protection structure for an optical instrument. Utility Model Content
