What causes damage to optical lenses?

Nov 03,2021

SIZE

Whether it is an optical lens made of inorganic or organic material, in daily use, friction with dust or grit (silicon oxide) will cause the lens to wear and scratches on the surface of the lens. Compared with glass flakes, organic materials have lower hardness and are more prone to scratches. Through the microscope, we can observe that the scratches on the lens surface are mainly divided into two types. One is the scratches caused by grit, which is shallow and small, and it is not easy for the wearer to detect; the other is the scratches caused by the larger grit. , Deep and rough periphery, in the center area will affect vision.
Then, by coating the lens, wear will be reduced, and the quality of the lens can be improved and the service life of the lens can be prolonged.
During the installation of the optical lens, if the method is not correct, the lens will be contaminated. Therefore, the operating procedures must be followed.
If a large number of lenses need to be installed and disassembled, it is necessary to design a fixture to complete the task. A dedicated fixture can reduce the number of contact with the lens, thereby reducing the risk of lens contamination or damage.
In addition, if the lens is not installed correctly, the laser system will not work normally, or even be damaged. All CO2 laser lenses should be installed in one direction. Therefore, the user should confirm the correct orientation of the lens.
