Detailed Product Description

Parameter

Optical specifications: 9.1mm Focal length, F-number F1.0. Working wavelength covers standard long-wave infrared 8–12μm. Diagonal field of view reaches 62.4°, horizontal 48.1°, vertical 38.5°, offering wide-area observation capability.

Detector matching: Optimized for 640×512 detector resolution, 12μm pixel pitch uncooled infrared detectors, perfectly matched for mainstream compact thermal sensor modules.

Mechanical & environmental specs: M17×0.5 threaded mount for easy assembly. Focus range 3m to infinity, supporting both near-distance and long-distance target detection. Operating temperature spans -40℃ ~ +80℃ to adapt extreme climates. Front element reaches IP67 ingress protection.

Optical quality metrics: ≥90% optical transmittance, ≥84% relative illumination; distortion controlled below -10%. Exposed optics adopt HD anti-reflection coating.

Performance Advantages

Ultra-large F1.0 aperture: Collects more infrared radiation, significantly improving imaging sensitivity under low-temperature, low-radiance environments and boosting detection distance.

High transmittance & HD coating: ≥90% transmittance reduces infrared signal loss; HD coating suppresses surface reflection, enhances image contrast and reduces ghost images.

Excellent edge illumination: Relative illumination ≥84% ensures uniform brightness across the whole image frame, avoiding dark corners commonly seen on wide-angle infrared lenses.

IP67 front waterproof design: The front optical element resists dust and water splashes, suitable for outdoor all-weather use without extra protective housings.

Wide temperature adaptability: Stable performance from -40℃ to +80℃; minimal thermal defocus eliminates frequent refocus demands in temperature-varying working conditions.

Compact M17×0.5 mount interface: Small mounting footprint, convenient for integration into miniature thermal cameras, drone payloads and handheld thermal devices.

Application Field

Security & perimeter surveillance: Outdoor border defense, factory perimeter monitoring, unattended site early warning, detecting intruders in complete darkness.This is also a core business segment of Shanghai Silk Optical Technology Co., Ltd.
