High-Performance Infrared Lens for Thermal Imaging Applications

●Product Description

‌Core Materials & Technology‌

‌Germanium (Ge) Lenses‌:
Wavelength ‌1.8–23μm‌, blocks visible light, Knoop hardness ‌780‌ for rugged applications (max. temp. ‌<100°C‌)‌.

‌Zinc Selenide (ZnSe) Lenses‌:
Low absorption at ‌10.6μm‌ (CO₂ lasers), range ‌0.6–21μm‌, avg. transmission ‌70%‌ (up to ‌>99%‌ with AR coating), temp. limit ‌<250°C‌‌.

‌Fluoride Lenses (CaF₂/BaF₂/MgF₂)‌:
BaF₂: Broadband transmission, stable up to ‌800°C‌ (dry environments);
MgF₂: Range ‌0.12–7μm‌, chemical/laser damage resistance, lowest refractive index (‌1.413‌) among IR materials‌.

‌Design Advantages‌
‌Aberration Control‌: Aspheric and achromatic doublet designs minimize spherical/chromatic aberrations for sharper thermal imaging‌1.
‌Coatings‌: Multi-layer AR coatings enhance transmission (MWIR: ‌3–5μm‌, LWIR: ‌8–14μm‌) and durability‌.

‌Applications‌
‌Thermal Imaging‌: Night vision, firefighting, industrial temperature monitoring;
‌High-Power Lasers‌: Beam focusing for CO₂ laser cutting/welding;
‌Spectroscopy‌: Trace gas detection (mid-IR) and environmental analysis‌13.

‌Customization Services‌
Tailored IR lenses, windows, filters, and optical assemblies with end-to-end support from prototyping to mass production;
Advanced metrology labs ensure surface accuracy ‌λ/4‌ and tolerance ‌±0.02mm‌‌13.

●Differentiation Highlights

‌Extreme Environment Solutions‌: Diamond-like carbon (DLC) coatings for lenses in high-temp/humidity/corrosive conditions;
‌Rapid Delivery‌: Standard lenses in ‌48-hour‌ stock, custom orders delivered in ‌<4 weeks‌‌1.
