개요
The 4.6mm F1.0 640×512 M19-3 LWIR 열적외선 카메라 렌즈 고성능이다, uncooled infrared lens designed specifically for thermal imaging applications. Featuring an ultra-fast F-number of 1.0 and a wide field of view, this compact lens is optimized for 640×512 resolution detectors with a 12μm pixel pitch. Its robust athermalized optical design ensures consistent image quality across a wide temperature range (-40°C ~ +60°C), making it ideal for demanding outdoor and industrial environments. With an IP67 sealing rating and lightweight construction, it offers durability and ease of integration into various thermal camera systems.
Features
- Ultra-Low Light Performance: Bright F/1.0 aperture allows for maximum infrared light collection, enhancing sensitivity in low-contrast scenes.
- Wide Field of View: Diagonal FOV ≥100°, providing extensive coverage for surveillance and monitoring.
- Athermalized Design: Optical athermalization maintains focus and image clarity without mechanical adjustment across extreme temperatures.
- High Transmission & Uniformity: Average transmittance ≥90% and relative illumination >80% ensure bright, 분명한, and uniform images.
- 엄격한 & 콤팩트: 경량 (<26g) and small form factor (≤φ24mm × L26mm) with IP67 ingress protection against dust and water.
- Broad Spectral Range: Optimized for the standard long-wave infrared (LWIR) band of 8~12μm.
- Flexible Focus: Continuous focus range from 0.3m to infinity.
