Clamping device for chemical membrane optical element

Abstract

The invention discloses a clamping device for a chemical membrane optical element. The clamping device comprises a hanging beam, clamping beams, a bearing beam and sealing plates; the hanging beam, the clamping beams and the bearing beam form a square frame, the bottom frame is the bearing beam, the left frame and the right frame are the two oppositely arranged clamping plates, and the top frame is the hanging beam; the inner sides of the hanging beam, the clamping beams and the bearing beam are provided with clamping grooves; the sealing plates are fixed to the front and the back of the square frame through sealing plate bolts on the hanging beam; the clamping device for the chemical membrane optical element is adjustable, clean delivery of the chemical membrane optical element in the operation processes such as transportation, storing, transfer, inspection and surface observation can be kept, non-contact operation of the optical element light transmission surface is achieved, stressuniformity of the optical element in the clamping process is protected, and additional pollution and stress are not likely to be generated. The clamping device for the chemical membrane optical element is suitable for optical elements of various specifications and shapes to use.

Description

technical field [0001] The invention belongs to the field of high-energy and high-power large-scale laser devices, and in particular relates to a clamping device for chemical film optical elements. Background technique [0002] In large-scale laser devices, laser optical thin films can be divided into two types according to the preparation method, namely physical method (vacuum evaporation method) and chemical method (including chemical vapor deposition and chemical solution deposition). With the gradual upgrading of inertial confinement fusion (ICF) high-power solid-state laser devices, higher requirements are put forward for the laser load capacity of optical thin films. At the same time, the coating of large-aperture optical components and reasonable economic problems have become insurmountable by traditional physical coatings. difficulties. Sol-gel chemical coating has attracted great interest from ICF research institutions in various countries due to its low cost, simp...
