CO2 Laser Protective Window ZnSe 38.1x3mm with DLC Coating for CO2 Laser Cutter Focus Lens

Size 38.1 x 3 mm Product overview This optical protective window and reflector assembly is designed for CO2 laser systems and other infrared laser applications. The protective window substrate is available in zinc selenide (ZnSe) by default, with germanium (Ge) available as an alternative. Coating options include antireflective thin film, diamond like carbon DLC coating, or uncoated. DLC is recommended for harsh environments where returned slag or debris can damage downstream optics. Custom antireflection films for specific wavelengths can be provided on request. Key benefits Protects downstream optics from contamination and mechanical damage while maintaining optical transmission for infrared lasers. Coating options let you choose the balance of reflectivity, durability, and environmental resistance for your application. Precision manufacturing and doublesided solid coating deliver consistent optical performance and long working life. DLC option increases resistance to abrasion and repeated surface cleaning in demanding production environments. Main features Size: 38.1 x 3 mm. Substrates: ZnSe standard, Ge optional. Coatings: Antireflection thin film, DLC coating, or uncoated. Copper reflector mirror option offers good optical characteristics for CO2 laser engraving systems. Dielectric film reflector option uses single crystal silicon substrate with dielectric coating to provide reflectivity and low loss for CO2 wavelengths. Doublesided solid coating for improved wiping resistance and extended service life. precision processing including slicing, polishing, and grinding to tight tolerances. Designed to tolerate higher operating temperatures to improve conversion efficiency in laser systems. Surface properties: lightweight, wiperesistant, and resistant to oxidation when dielectric or metal coatings applied. Compatibility and performance Specifically suited for CO2 laser beams and other infrared laser systems where ZnSe or Ge optics are appropriate. Available reflector types support reflectivity for efficient beam control and minimal energy loss. Custom antireflection coatings available to match specified wavelengths and system requirements. Typical applications CO2 laser engraving and cutting machines as a protective window or mirror component. Industrial laser processing stations where returned slag or particles risk damaging downstream optics. Optical benches and research labs requiring precision infrared windows and reflectivity mirrors. Notes Appearance may vary slightly due to monitor display differences. Coating and substrate choices affect optical transmission and durability; select the option that matches your system wavelength and environmental conditions.
