Fixed Athermalized IR Lens 35mm f/0.8
The GLA3508D features passive athermalization, ensuring sharp, stable thermal images across a wide temperature range (−40 °C to +85 °C) without the need for refocusing. Designed for the 8–12 µm spectral band, it offers reliable performance in compact, rugged housings. Ideal for UAVs, thermal imaging cameras, security systems, and industrial or defense applications.
- Focus: fixed athermalized
- Interface: thread
- Compact and lightweight: strong universality and multiple application scenarios (esp. UAVs）
- External coating: great transmission performance and low reflection
