Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] as attached figure 1 or attached figure 2 As shown, an ultra-clean vacuum sealing method for an optical lens, the installation device 2 and the optical lens 1 are sealed and fixed by a soft metal sealing ring 3 to control the pollution of organic pollutants caused by the rubber sealing ring. The soft metal sealing ring 3 is made of aluminum, tin, lead, indium, gold, silver or their alloy materials. The cross section of the soft metal sealing ring 3 is circular or rectangular or circular or crescent-shaped, the shape of the soft metal sealing ring 3 and the sealing groove 4 is circular or square, and the soft metal sealing ring 3 The circumference corresponds to the circumference of the sealing groove 4. The cross-section of the soft metal sealing ring 3 can be circular or square or circular or crescent-shaped, and a sealing ring with a circular cross-section...

Abstract

The invention discloses an ultra-clean vacuum sealing method for an optical lens. An installation device and the optical lens are sealed and fixed through a flexible metal sealing ring. The ultra-clean vacuum sealing method for the optical lens can solve the vacuum pollution problem caused by sealing through a traditional sealing ring and the problem of high cost of sealing through a metal flange, and replacement of the lens is simple and easy.

Description

technical field [0001] The invention relates to a technology for controlling pollutants caused by optical lens sealing in a system requiring vacuum cleanliness, in particular to an ultra-clean vacuum sealing method for optical lenses. Background technique [0002] In high-power laser pump light sources and applied optical systems, extreme ultraviolet light source optical systems, and ultra-clean analytical instruments, a large number of optical lenses are used, and some lenses also need to undertake the role of isolation between spaces with different pressure differences. Generally, the methods used are: Two types: one is the vacuum sealing scheme using rubber rings; the other is sealing the lens on the CF stainless steel flange through the glass-to-metal sealing scheme, through the knife edge on the stainless steel flange and the oxygen-free copper sealing ring Press and seal to realize space vacuum isolation. The first solution is simple and easy to operate, but because t...
