High-Performance ZnSe Windows – Low Absorption IR Windows for CO₂ Lasers & Thermal Imaging
Our ZnSe windows are fully customizable to match your application requirements:
-
Diameter / Dimensions: 5 mm to 300 mm, with tolerance down to ±0.03 mm
-
Thickness: 0.5 mm to 20 mm, optimized for pressure differentials and laser power handling
-
Surface Quality: 20-10 or 10-5 scratch-dig per MIL-PRF-13830B
-
Flatness: λ/4 to λ/10 at 632.8 nm
-
Parallelism: ≤ 3 arcminutes, with high-precision options ≤ 10 arcseconds
-
Coatings: AR (Anti-Reflection) at 10.6 µm, BBAR for 3–5 µm or 8–12 µm, dual-band coatings, or DLC (Diamond-Like Carbon) for environmental protection
-
Clear Aperture: Typically ≥ 90% of central diameter
-
Edge Finish: Fine-ground, beveled, or polished edges
-
Custom Shapes: Round, rectangular, or stepped configurations available
Typical Applications:
-
CO₂ laser output windows and vacuum isolation windows
-
Laser processing machine protective windows (cutting, welding, marking)
-
Thermal imaging and FLIR camera protective windows (MWIR/LWIR)
-
Infrared spectroscopy sample cell windows (FTIR, NDIR gas analyzers)
-
Vacuum chamber viewports for IR optical access
-
Pyrometer and radiometer sensor windows
-
Military targeting and reconnaissance pod windows
-
Medical laser delivery system windows (CO₂ surgical lasers)
With high damage threshold (> 1 kW/cm² CW at 10.6 µm) and excellent chemical resistance, ZnSe windows deliver reliable long-term performance in both laboratory and field-deployed systems.
