Product Description
Ø1/2" and Ø1" Zinc Selenide (ZnSe) Bi-Convex Lenses are available with a broadband AR coating optimized for the 7 µm to 12 μm spectral range deposited on both surfaces. This coating greatly reduces the high surface reflectivity of the substrate, yielding an average transmission in excess of 97% over the entire AR coating range.
Bi-convex lenses are popular for many finite imaging applications. Both surfaces are spherical and have the same radius of curvature, minimizing aberrations in situations where the object and image distances are equal or nearly equal. ZnSe lenses are particularly well suited for use with high-power CO2 lasers.plano-convex lenses are usually preferred.
- AR Coating Optimized for the 8 - 12 µm Range
- Choose from Ø1/2" or Ø1"
- Ideal for CO2 Laser Applications
Due to Low Absorption Coefficient
