Focusing lens:

We are professional manufacture of lens:

Packed lens:

We have multi size machine parts for Precitec, trumpf, highyag, Laser Mech, laser welding machines and so on. The material we have K9(suitable for machine power less than 500W), China Quartz (suitable for machine power from 500W to 1000W), Imported quartz (suitable for machine power higher than 1000W)and we can provide as your sample. Many types of mirrors have in stock, We also supply Ceramic, nozzle, cable and so on.

Focus lens cleaning and maintenance:

1. Focus lens material for the ZnSe or zinc arsenic, relatively brittle, fragile; in the disassembly should pay attention to: not too hard, and hard objects can not collide. The surface of anti-reflective film, fear of pollution, fear of wet, afraid of oil, fear of scratch; it is required in the work to provide dry, to oil the air, clean recommended cleaning equipment and cleaning methods.

2. Equipment must ensure that there is sufficient pressure. Before the work can be extended into the focus of the mirror out of the mouth of light (gas nozzle) to check whether there is a gas blowing? Is the air pressure sufficient?

3. Before the first start-up work every day, please remove the lens tube with focus lens to observe whether the focus lens contamination. Focus lens cleaning principle is: no pollution as far as possible not to clean, there is pollution need to clean in time!

4. Cleaning steps: 1. Loosen the fastening screws, followed by removing the gas nozzle and tube; first blow the dust off the lens surface; 2. If you really need to clean the lens, can only use laboratory-grade paper Soft cotton balls, dipped in the right amount of acetone or a high degree of alcohol, gently clockwise from the center of the lens rotation to rub the edge. When necessary, both sides of the lens need to be clean, scrubbing should be careful and meticulous. 3.Install a good tube and gas nozzle, adjust the focal length, tighten the fastening screws. 5. If the focus lens is too seriously contaminated or a long time can not be effectively cleaned, resulting in can not clean, or focus lens on the anti-reflective film off, you need to replace the focus lens.

6. General 2-inch focal length lens (reflected in the workpiece surface to the nozzle from the bottom of the distance) is about 6 ~ 7mm, the user can be adjusted according to the actual situation, the most appropriate focal length.

7. Keep the focus lens clean, cutting, carving and strong effect of the guarantee. 8. New equipment in the newly installed laser lens, be sure not to force the lens will lead to serious damage to the optical lens
