Features:

1. Adopt Chemical Vapour Deposition and High quality ZnSe Crystal.

Widely Used for laser processing,such as cutting,drilling,Welding sculpture,and kinds of laser cutter system.

2.To meet different market demand,convexo-plane and Crescent Can be customized.

Can Endure High power density,stable coating,Wipe-resistant,two-sided anti- reflecting film, location of 10.6μm≥99.8%

3.Optimum design from diffraction and aberration,A series of products have been developed to minimize the diameter of actual focusing spot under the same focal length.

Focal Length:
Laser focusing lenses are usually meniscus shaped，The convex face is upward when installed，Focus distance usually means the distance between the lens and worktable.

Note:

1.Keep the lenses clean all the time, To Avoid contamination with impurities to prevent uneven heating from being cracked by laser.

2.The position of the barrel is fine-tuned after replace the lens, And fix to the best position.

3.Guarantee the normal operation of cooling system.

4.Please pay more attention to dimming, the light path will easily break the lens when it is on the edge of the lens.

5.When cleaning lenses, please use absolute alcohol and soft wiping paper to gently wipe clockwise.
