10.6μm : CO2 Optics
ZnSe Meniscus Lenses
Meniscus lenses allow minimal spherical aberrations when a parallel beam enters the convex surface. This results in a minimum focal spot size for the incoming collimated light source. All plano convex and meniscus lenses shown have positive focal lengths. Negative focal lengths are available upon request.
ZnSe Meniscus Lens Specifications
- Diameter Tolerance: +0.000" / -0.005"

- Sphericity: < 1/40th wave at 10.6 microns
- Surface Quality: 40-20 Scratch Dig
- Focal Length Tolerance: ±2%
- Absorption: 0.25% total
- AR Coating Reflectivity: R < 0.5% per surface at 10.6 microns
Tips & Warnings
After performing air cutting operations, use acetone and then vinegar to clean your laser cutting lens.
