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:
| Material | Wavelength Range | Key Features |
|---|---|---|
| Germanium (Ge) | 2μm – 14μm | High transmission, durable, widely used in thermal cameras |
| Silicon (Si) | 1μm – 6μm | Lightweight, cost-effective, good for mid-IR applications |
| Zinc Selenide (ZnSe) | 0.6μm – 12μm | Low absorption, ideal for CO2 laser systems |
| Chalcogenide Glass | 3μm – 12μm | Cost-effective alternative to Germanium |
| Sapphire (Al₂O₃) | 3μm – 5μm | Scratch-resistant, used in harsh environments |
We offer custom infrared lenses made from these materials based on your application needs.
