Description
1. Material: GaAs, Diam: 20mm/ 0.79", Focal length: 38.1mm/1.5", Thickness: approximate 2.2mm / 0.087", Usage: CO2 Laser Lens for higher power CO2 laser engraving, cutting machine.2. Compatible power: Dia.15mm/18mm/19.05mm/20mm, 40W-200W; Dia.25mm/25.4mm, 40W-400W; Dia.27.94mm/28mm, Up to 600W CO2 laser resistance;.3. High Transmittance: To obtain superior transmittance, GaAs crystals are grown by Chemical Vapor Deposition process. Please note: GaAs Focus lens appear in different colors under different light..4. GaAs material is a chemically inert, non-hygroscopic and highly pure product that has high resistance to thermal shock and stability in virtually all environments, can work under higher temperature and with longer work life..5. Double-sided Solid Coating, demonstrates superior CO2 laser transmittance and is employed as the transmission optical components used in CO2 laser processing.
