20Mm Diameter Znse Focal Lens For Co2 Laser Cutter Engraver Fl 508Mm

Specification : Model : DN20FL50.8 Material : ZnSe Diameter : 20mm Focal Length : 50.8mm Edge Thinckness : 2.2mm Aperture : 90 procent of the Diameter Tolerance of Thickness 0.25mm Tolerance of Diameter : 0/-0.13mm Effective Focal Length : 2 procent Anti-Reflective Coating : at 10.6 m Surface Quality : 40-20 Surface Figure at 0.63 m : /2 per 1 inch Dia Coating Transmittivity Per surface at 10.6 m : 99.50 procent Features : - ZnSe is used for optical windows, lenses, mirrors, prisms and optical blanks, plates, disks, sheets, slabs particularly for infrared applications - Zinc Selenide (ZnSe) is 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 Chemic Lees meer over de 20Mm Diameter Znse Focal Lens For Co2 Laser Cutter Engraver Fl 508Mm van huismerk in de productgroep tools
