Clamp and clamping method for large-diameter plane optical element

Abstract

Provided are a clamp and a clamping method for a large-diameter plane optical element. The clamp comprises a large-diameter plane optical element press plate, an elastic pivot, a transformation thin plate frame, an inner hexagonal cylindrical head screw, a boss, a lens frame, a rotational shaft and a support. The clamp and the clamping method utilize a metal structure to directly clamp the large-diameter optical element, can produce no optical element clamping stress under the condition that surface processing accuracy of a metal clamping frame is reduced and the optical element is in any inclination angle. Simultaneously, the metal structure is utilized to conduct direct clamping, thereby well avoiding organic pollution caused by stress-free clamping of tradition organics. The clamp the clamping method can be widely applied to clamping of the large-diameter plane optical element in optical engineering and optical experiment devices and has strong practicability.

Description

technical field [0001] The invention relates to an optical element, in particular to a fixture and a clamping method for a large-diameter planar optical element, which can be widely used in the clamping of a large-diameter planar optical element in optical engineering and optical experimental devices, especially in vacuum environments and cleanliness In a demanding environment, this method can also meet the clamping of various shapes and large-diameter planar optical components, and meet the requirements of no pollution and no stress. Background technique [0002] At present, the development trend of high-power lasers is large-caliber, high-throughput, and arrayed. To achieve high-throughput laser transmission, a clean, dry, and pollution-free environment is required. The traditional stress-free clamping of organic matter is obviously not possible. meet that requirement. This is mainly because the traditional stress-free clamping method of organic matter uses silica gel, va...

Problems solved by technology

[0002] At present, the development trend of high-power lasers is large-caliber, high-throughput, and arrayed. To achieve high-throughput laser transmission, a clean, dry, and pollution-free environment is required. The traditional stress-free clamping of organic matter is obviously not possible. meet the requirement

This is mainly because the traditional stress-free clamping method of organic matter uses silica gel, vacuum rubber or cork, etc., which will produce pollutants - aerosols under the direct or indirect irradiation of high-power lasers, which are distributed in the entire experimental environment and affect the optical components. Contamination resulting in damage or damage growth of optical components under laser irradiation
