Embodiment 1

[0039] like figure 1 As shown, for the polished D45.6 zinc sulfide lens, this embodiment provides a surface treatment process for the zinc sulfide lens, including the following steps:

[0040] (1) Wipe with an aqueous solution of citric acid after polishing. In the aqueous solution of citric acid, the mass ratio of citric acid to water is 1:5, the purity of the citric acid is 99%, and the water is deionized water. During the wiping process, wrap the index finger with a dust-free cloth, drip the aqueous solution of citric acid on the index finger, and gently wipe the lens evenly in one direction until the surface of the lens is observed under a strong light, and the surface is free of dirt. The cleanliness level of the dust-free cloth is not lower than 100. During the wiping process of the dust-free cloth, it is necessary to keep the wiping part of the dust-free cloth without wrinkles and the surface is smooth;

[0041] (2) Configuring a polishing liquid, the polishing liquid ...

Abstract

The invention belongs to the field of lens surface treatment, and discloses a surface treatment process of a zinc sulfide lens, which comprises the following steps: (1) citric acid wiping; (2) preparing a polishing solution; (3) wiping with a polishing solution; (4) ultrasonic cleaning; and (5) entering a subsequent film coating procedure after the inspection is qualified. According to the zinc sulfide lens surface treatment process, the zinc sulfide lens can be better cleaned, the appearance problems that the surface of the zinc sulfide lens is dirty and white after film coating and the like are solved, and the yield of the zinc sulfide lens in the production process is increased.

Description

technical field [0001] The invention belongs to the field of infrared product surface treatment, and more particularly relates to a surface treatment process for zinc sulfide lenses. Background technique [0002] Zinc sulfide lens is mainly used as the mainstream product of infrared lens. It has excellent band characteristics and can penetrate visible waves to medium and long wavelengths. Surveillance, vehicle infrared night vision, fire protection, power detection, etc. have huge applications. [0003] Zinc sulfide lenses are coated before delivery, and undergo surface treatment before coating. The current common surface treatment process is: after polishing, use a clean cloth dipped in alcohol and acetone to wipe by hand before coating. The process has the following problems: [0004] (1) When wiping by hand, excessive wiping may be performed to remove visible dirt on the surface. In the specific wiping process, the alcohol / acetone wiping time is too long and the wiping ...
