Detailed Product Description

Parameter

1. Optical Specifications

This infrared optical lens carries 4.1mm focal length alongside F1.0 ultra‑large aperture. The ultra‑large aperture improves infrared light intake capacity significantly. Such optical performance constitutes the core guarantee for clear image output of this thermal infrared lens under low‑temperature and low‑radiance operating conditions.

2. Detector Matching

BOSHI Optical Technology designs this lens to pair with 640×512 resolution, 12μm pixel infrared detectors. It maintains high compatibility with mainstream uncooled thermal sensor formats. The well‑matched hardware characteristic eliminates imaging deviation triggered by mismatching conditions between lens and sensor chip.

3. Field of View

The lens supports 130 degree diagonal, 102 degree horizontal, 83 degree vertical wide FOV. Equipment obtains large‑range scene coverage without additional mechanical scanning assemblies. This property simplifies the overall mechanical structure design of thermal imaging equipment.

4. Focus Performance

Continuous focus range spans 0.5 meter to infinity. The focus performance balances close‑range inspection operation and long‑distance surveillance tasks. It broadens the usable distance boundary of this 4.1mm focal length lens for actual site deployment.

5. Environmental and Mechanical Index

Its operating temperature scope covers minus 40 degree Celsius to plus 80 degree Celsius. Front lens surface reaches IP67 waterproof and dustproof standard. It uses M22×0.5 mount standard thread interface to streamline assembly work. Net weight sits near 25 gram, which creates favorable premise for lightweight equipment product development.

6. Imaging Quality Indicators

With AR anti‑reflection coating equipped, optical transmittance exceeds 88 percent. Relative illumination stays above 80 percent. Distortion value keeps below 45 percent. This group of indicators realizes good balance between wide‑angle imaging trait and real‑world image quality performance of the infrared optical lens..

Performance Advantages

1. Excellent Low‑Light Thermal Sensitivity

F1.0 maximum aperture raises radiant energy collection efficiency. When working within dim and low‑radiation surroundings, this thermal infrared lens can noticeably boost thermal image contrast. It lowers image blurring probability when target infrared signal turns weak, and delivers stable picture foundation for low‑radiance scene observation.

2. Ultra‑Wide Scene Coverage

The 130 degree diagonal wide FOV allows single hardware unit to monitor expanded spatial scope. Project implementers may cut the total number of thermal cameras needed for full‑area monitoring accordingly. This change brings direct reduction for overall system construction expenditure. BOSHI Optical Technology optimizes optical path to guarantee usable picture quality under such large viewing angle condition.

3. Reliable Imaging Uniformity

Relative illumination higher than 80 percent effectively restrains vignetting issue. Image frame maintains consistent brightness across all areas. Transmittance over 88 percent reduces infrared energy loss inside optical transmission route. BOSHI Optical Technology implements repeated calibration for this infrared optical lens. The calibration work ensures steady image output during long‑duration continuous operating status.

4. Robust Environmental Adaptability

IP67 front lens protection plus wide temperature working scope enables stable operation amid rain, dust, extreme cold and high‑heat environments. The thermal infrared lens does not demand frequent manual maintenance work. It fits outdoor installation and harsh industrial field deployment scenarios.

5. Compact Structure for Convenient Integration

25 gram lightweight body and standard M22×0.5 mount decrease mechanical design difficulty for miniaturized thermal imaging devices. Product developers can reduce structural modification workload in the course of product integration procedure. It shortens the research and development cycle for terminal thermal hardware.

6. Versatile Focus Adjustment Capacity

0.5 meter minimum focusing distance supports close‑range target detection. Compared with purely long‑distance fixed‑focus lens solutions, this 4.1mm focal length product extends application coverage. It fulfills mixed‑distance observation demands from multiple practical projects.

Application Fields

1. Perimeter Security Monitoring

This infrared optical lens with wide FOV supplies wide‑angle thermal surveillance capacity for factory premises, park zones, border regions and residential compounds. It completes intrusion detection tasks round the clock without visible light input. Perimeter security monitoring counts as one core application direction for product series from BOSHI Optical Technology.

2. Industrial Thermal Inspection

The thermal infrared lens supports device temperature screening, electrical cabinet fault diagnosis, pipeline thermal leakage check and factory safety patrol work. On‑site staff can discover abnormal heat sources timely so as to prevent potential industrial safety incidents. 640×512 resolution matching feature guarantees fine thermal detail capture in industrial inspection missions.

3. Smart Transportation and Vehicle Vision

Users may deploy the lens for automotive thermal night vision and road traffic monitoring work. Under foggy, night‑time and low‑visibility circumstances, its 12μm pixel matching performance assists pedestrian as well as obstacle identification work. It improves safety guarantee level for intelligent traffic related systems.

4. Unmanned Systems Payload

Benefit from 25 gram lightweight property, this infrared optical lens serves as light‑weight thermal payload for unmanned aerial vehicles, robots and unmanned ground vehicles. It executes search and rescue activity, wildfire risk monitoring and terrain patrol assignments. M22×0.5 mount brings quick mounting advantage for unmanned platform payload assembly.

5. Public Safety and Emergency Rescue

For fire‑fighting thermal positioning and search‑and‑rescue assignments, the lens performs well inside dark, smoky or visually blocked surroundings. Thermal signals can penetrate partial smoke disturbance and lock target location. Wide FOV helps responders finish fast large‑area site scanning during emergency operations.
