Detail Information
Edge Blackened Meniscus Concave-Convex Infrared Lens With Multi Optional IR Crystal Substrates
Felix Glass black-edge meniscus infrared lens is a single-element concave-convex meniscus optical part specially designed for all types of infrared optical systems. We provide six mainstream infrared crystal substrates for customers to select: Calcium Fluoride (CaF2), Zinc Selenide (ZnSe), Zinc Sulfide (ZnS), Germanium (Ge), Magnesium Fluoride (MgF2), Silicon (Si), covering deep UV, near-infrared, mid-wave infrared and long-wave infrared full spectrum demands.
The lens adopts meniscus concave-convex curvature design, which can realize precise focusing or divergent shaping of infrared beam, effectively reduce spherical aberration compared with flat lens. The full circumference edge is coated with matte black paint, which absorbs scattered stray light reflected from lens edge, eliminates ghost image and improves imaging contrast of infrared thermal cameras and infrared laser equipment. Custom multi-band AR anti-reflection coating can be deposited on two optical surfaces to maximize infrared transmittance.

Standard FAQ
1. What is the function of black edge coating on this meniscus infrared lens?
Matte black paint on lens edge absorbs stray light reflected from crystal sidewall, eliminates ghost image and light flare, improves imaging contrast and signal-to-noise ratio of infrared thermal & laser systems.
2. How to choose the suitable substrate among CaF2, ZnSe, ZnS, Ge, MgF2, Si?
Select according to working wavelength: CaF2/MgF2 for UV-MWIR spectrum; ZnSe/ZnS for multi-spectrum & CO₂ laser; Ge for pure 8-14μm thermal imaging; Si for 1-7μm mid-infrared laser ranging.
3. Can I customize focal length and anti-reflection coating for this meniscus lens?
Yes, we support custom positive/negative focal length, lens diameter, and AR coating optimized for target infrared band (3–5μm / 8–14μm /10.6μm CO₂ laser).
4. What infrared equipment is this multi-substrate meniscus lens suitable for?
It matches LWIR thermal imagers, CO₂ laser equipment, industrial infrared temperature measuring instruments, laboratory spectrometers and aerospace infrared detection optical modules.
