The invention discloses an atmosphere protection optical lens cone with the high air tightness and the high precision. The atmosphere protection optical lens cone comprises a first lens frame pressing ring, a first lens frame, a first lens frame glue injection groove, a first lens pressing ring, a first lens, a first lens sealing ring, a lens cone body, a second lens, a second lens frame, a second lens frame vent hole, a center adjusting jackscrew, a second lens pressing ring, a second lens center adjusting ring, a second lens frame pressing ring, a second lens frame pressing ring vent hole, a connecting screw, a lens cone sealing ring, a box body, a one-way inlet valve and a one-way air discharging valve. The atmosphere protection optical lens cone is simple and reliable in structure; an optical lens can be adjusted precisely, the air liquidity inside a mechanism is good, and the inner portion of the mechanism can be evenly filled with a protection atmosphere; seams and gaps outside the mechanism are avoided and the atmosphere protection optical lens cone is good in air tightness.
Description
technical field [0001] The invention relates to precision optical instruments, in particular to an atmosphere-protected high-airtight and high-precision optical lens barrel. Background technique [0002] High-precision optical lenses and lens barrels are important components of modern precision instruments. For the adjustment of the optical system, it is often required that the center distance of each optical mirror be accurate, the mirror surface and the optical axis be as vertical as possible, and the eccentricity be as small as possible. At the same time, some high-precision lenses and lens barrels also need atmosphere protection. For example, a certain lens needs to work at -50 ° C ~ 0 ° C. In order to prevent low temperature condensation in the cavity, it is necessary to replace the lens with nitrogen (or other pure gases). The air in the lens barrel cavity; another example: the optical mirror in a certain lens barrel uses a special coating, which is easily damaged whe...
