-
Centration: ≤ 3 arcminutes, with high-precision options ≤ 10 arcseconds
-
Coatings: AR (Anti-Reflection) at 10.6 µm, BBAR for 3–5 µm / 8–12 µm, or dual-band coatings for combined MWIR/LWIR operation
-
Lens Types: Plano-convex, bi-convex, meniscus, aspheric, or cylindrical profiles available
-
Edge Finish: Beveled or fine-polished edges for safe handling
Typical Applications:
-
CO₂ laser cutting, engraving, and marking machine focusing lenses
-
Beam expanders and collimators for industrial laser processing
-
Thermal imaging and FLIR camera objective lenses (MWIR/LWIR)
-
Fourier transform infrared (FTIR) spectroscopy optics
-
Infrared radiometry and pyrometry sensor optics
-
Medical laser surgical systems (CO₂ ablation)
-
Military targeting pods and missile seeker optics
With high damage threshold and low thermal lensing effect, ZnSe remains the industry standard for high-power infrared laser optics.
