Infrared Lens – High-Performance Optics for Thermal Imaging

What is an Infrared Lens?

An infrared lens is designed to focus and transmit infrared (IR) light, typically in the wavelength range of 3μm to 14μm. These lenses are essential for thermal imaging, night vision, and infrared sensing applications.

Thermal Imaging Lenses

Thermal imaging lenses are specially designed to capture infrared radiation and convert it into visible images. They are widely used in:
Security & Surveillance – Night vision cameras and border security
Industrial Inspection – Detecting heat leaks and machine faults
Medical Imaging – Fever screening and infrared thermography
Defense & Military – Target detection and tracking

Infrared Lens Material

Infrared lenses are made from special materials that allow IR light to pass through with minimal loss. Common infrared lens materials include:

MaterialWavelength RangeKey Features
Germanium (Ge)2μm – 14μmHigh transmission, durable, widely used in thermal cameras
Silicon (Si)1μm – 6μmLightweight, cost-effective, good for mid-IR applications
Zinc Selenide (ZnSe)0.6μm – 12μmLow absorption, ideal for CO2 laser systems
Chalcogenide Glass3μm – 12μmCost-effective alternative to Germanium
Sapphire (Al₂O₃)3μm – 5μmScratch-resistant, used in harsh environments

We offer custom infrared lenses made from these materials based on your application needs.
