ZnSe Window BBAR(3-12μm & 8-12μm)

High-purity CVD Zinc Selenide windows with dual-sided BBAR coatings, available in 3-12μm and 8-12μm bands. Features high infrared transmission and low absorption, ideal for CO₂ lasers and thermal imaging systems.

Description

Features:

Low dispersion
Available in both uncoated and anti-reflection (AR) coated versions
Ideal for thermal imaging, FLIR and medical systems

These 3mm-thick optical windows are fabricated from high-purity CVD Zinc Selenide (ZnSe), coated with dual-sided broadband anti-reflection (BBAR) film for 0° angle of incidence. Two wavelength coating options are provided to match mid-infrared and long-wave infrared application demands, effectively reducing Fresnel reflection loss and improving system optical efficiency.

3-12μm BBAR Coating
Covers the full mid-infrared band. Transmittance rises rapidly to over 90% from 3μm, and maintains a high transmission plateau across the entire 3–12μm range, suitable for broadband infrared systems.
8-12μm BBAR Coating
Optimized for the long-wave infrared (LWIR) atmospheric window. Delivers over 95% peak transmittance within 8–12μm, specially matched for thermal imaging and 10.6μm CO₂ laser applications.

Typical Applications:
CO₂ laser processing equipment, infrared thermal imaging cameras, infrared spectroscopy instruments, medical infrared diagnostic devices, industrial infrared detection systems.

Note: Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.
