Imported CVD zinc selenide material is a material with high purity, strong environmental adaptability and easy processing.
The lens has stable focusing, accurate and reliable focusing, better cutting and engraving effect, can withstand high power, and the surface film is firm, not easy to fall off, and resistant to friction.
High-purity zinc selenide double-sided reinforced coating, better temperature resistance, finer focusing, and light transmittance greater than 99.8%.
Notice:
1) Always ensure that the lens is clean and avoid sticking sundries to prevent uneven heating from being cracked by the laser.
2) After replacing the lens, fine-tune the position of the lens barrel and fix it to the best position.
3) Ensure the normal operation of the cooling system.
4) Note that when dimming, the optical path is easy to cause the lens to be broken when the light path is at the edge of the lens.
5) When cleaning the lens, please use anhydrous alcohol and a soft wipe to wipe gently.
