Detailed Product Description

3.1 Parameter

Optical Specifications: 4.1mm focal length paired with F1.0 ultra-large aperture. The large F-number enables high infrared light intake, critical for clear thermal images under low-temperature, low-radiance conditions.

Detector Matching: Designed exclusively for 640×512 resolution, 12μm pixel infrared detectors, perfectly matching mainstream uncooled thermal sensor formats.

Field of View: 130° diagonal, 102° horizontal, 83° vertical ultra-wide field of view, offering expansive scene coverage without mechanical scanning.

Focus Performance: Continuous focus range from 0.5m to infinity, supporting both close-range inspection and far-distance surveillance.

Environmental & Mechanical Index: Operating temperature spans -40℃ ~ +80℃; front lens achieves IP67 waterproof and dustproof rating. Adopts M22×0.5 standard thread mount for easy assembly; net weight is around 25g for lightweight equipment design.

Imaging Quality Indicators: AR anti-reflection coating, optical transmittance over 88%, relative illumination above 80%, distortion controlled under 45%.

3.2 Performance Advantages

Superior Low-Light Thermal Sensitivity: F1.0 maximum aperture greatly improves radiant energy collection, enhancing thermal image contrast in dim and low-radiation environments.

Ultra-Wide Coverage: The 130° diagonal wide FOV reduces the number of thermal cameras required for full-area monitoring, lowering overall system costs.

Stable Imaging Uniformity: >80% relative illumination effectively suppresses vignetting, ensuring consistent brightness across the whole image frame. Over 88% transmittance minimizes infrared energy loss.

Strong Environmental Durability: IP67 front lens protection and wide temperature working range enable stable operation in rain, dust, extreme cold and high heat without frequent maintenance.

Compact & Easy Integration: Lightweight 25g structure and standard M22×0.5 mount simplify mechanical design for miniaturized thermal imaging devices.

Flexible Focus Capability: 0.5m minimum focusing low distance supports close-target detection, broadening usable scenarios compared to fixed-focus lenses only for long distances.

3.3 Application Fields

Perimeter Security Monitoring: Wide-angle thermal surveillance for factories, parks, borders and residential zones, detecting intrusions day and night without visible light.This also constitutes one of the core business segments of Shanghai Silk Optical Technology Co., Ltd.

Industrial Thermal Inspection: Equipment temperature screening, electrical cabinet fault detection, pipeline thermal leakage inspection and factory safety patrol.

Smart Transportation & Vehicle Vision: Automotive thermal night vision, road traffic monitoring, pedestrian and obstacle detection under fog, night and low visibility conditions.

Unmanned Systems Payload: Lightweight thermal payload for UAVs, robots and unmanned ground vehicles for search & rescue, wildfire monitoring and terrain patrol.

Public Safety & Emergency Rescue: Firefighting thermal positioning, search-and-rescue missions in dark, smoky or obscured environments.

Agriculture & Environmental Monitoring: Vegetation temperature analysis, wildlife observation, environmental heat distribution tracking.
