focal length 1.5” 2” 2.5” 4” diameter 20mm zinc selenide focus lamp CO2 Laser cutting machine laser engraving machine accessories

1.High transmittance, high temperature resistance

 The lenses are made of zinc selenide,

The transmission loss of laser is small, the absorption is low, the transmittance is strong.

Light transmittance up to 99.8%, and can withstand up to 500W laser power.

2.Coating is not easy to fall off, wipe resistant

 Reinforced double-sided coating technology, coating firm, not easy to fall off, durable, wipe resistant, long service life

 3.Fine spot, fast cutting speed

 Lens cylinder polishing, increase light transmittance, reduce or eliminate stray light in the system, improve the ability of lens to withstand back reflection, make lens spot thinner, faster cutting speed.

 4.Complete specifications, a wide range of applications

 Full range of lens specifications, suitable for all kinds of laser cutting machine, engraving machine
