Lentille COLETECH HQ ZNSE pour Graveur Laser Co2 40W -100W D: 18mm FL: 4' 101.6mm: Bricolage. Lentille COLETECH HQ ZNSE pour Graveur Laser Co2 40W -100W D: 18mm FL: 4" 101.6mm: Bricolage. ZNSE Lens work with 35~100W CO2 Laser 。 ET=2.2mm 。 Diameter: 18mm,FL:4" 。 Can be use on engraving and cutting 。 Description du produit Couleur: Fl: 4" /101.6mm。 Meterial: ZNSE.。 Edge Thinckness: 2.5mm.。 Tolerance of Thickness : 0.010'' 。 Edge thickness variation (ETV): <= 0.002'' 。 Aperture: 90% of the Diameter 。 Face accuracy (radial deviation / irregularity) at 0.63um :/<= 0.20%。 AR Coating Reflectivity Per surface at 10.6 microns :/<= 0.20%。 Work with 30W- 100W CO2 Laser Engraver Cutter.。 ZnSe is used for optical windows, lenses, mirrors, prisms and optical blanks, plates, disks, sheets, slabs particularly for infrared applications.Zinc Selenide (ZnSe) - transparent in wide spectral range from yellow (visible) to far IR. ZnSe material is a chemically inert, non-hygroscopic and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined. To obtain superior transmittance, ZnSe crystals are grown by Chemical Vapor Deposition process . Zinc Selenide is polycrystalline material, demonstrates superior CO2 laser transmittance and is employed in the transmission optical components used in CO2 laser processing. 。 。 。 。
