High-Performance Infrared Lenses for Thermal Imaging | China Suppliers & Factory for Custom Optical Solutions
Product Description
Wavelength: 1.8–23μm
Blocks visible light. Knoop hardness 780 for rugged applications (max. temp. <100°C).
Wavelength: 0.6–21μm
Low absorption at 10.6μm (CO₂ lasers). Avg. transmission 70% (up to >99% with AR coating), temp. limit <250°C.
BaF₂: Broadband transmission, stable up to 800°C (dry environments).
MgF₂: Range 0.12–7μm, chemical/laser damage resistance, lowest refractive index (1.413).
- Aberration Control: Aspheric and achromatic doublet designs minimize spherical/chromatic aberrations for sharper thermal imaging.
- Coatings: Multi-layer AR coatings enhance transmission (MWIR: 3–5μm, LWIR: 8–14μm) and durability.
- 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 analysis.
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 ±0.02mm.
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 weeks.
