Injection molding of capsule shell, has a high transmittance optical effect, small size, light weight, and is made of corrosion-resistant polymer material, which does not rupture.

BOSHI Optical Technology presents the PL‑02934H‑M12, a high‑performance wide‑angle fixed lens engineered for 1/4" format sensors. With a 2.9mm focal length and a fast F3.4 aperture, this lens delivers a generous 119° diagonal field of view, making it ideal for applications that require broad scene coverage in tight spaces. Its all‑glass construction (3 elements) ensures thermal stability and consistent image quality across a wide temperature range. The lens features a controlled chief ray angle of less than 6.63°, which minimises colour shading and maintains colour accuracy when paired with modern CMOS sensors. Despite its compact 8.9mm total track length, the mechanical back focal distance of 2.46mm offers flexible integration with standard M12 mounts. BOSHI Optical Technology has carefully balanced the optical design to achieve a TV distortion of ‑14.27% – a typical value for ultra‑wide lenses that can be digitally corrected – and a relative illumination of 30% at the edge, ensuring usable brightness even in low‑light conditions. This lens is a cost‑effective solution for embedded vision, security cameras, in‑vehicle surround‑view systems, and industrial inspection where a 2.9mm focal length and wide 119° coverage are essential. Whether you are designing a dashcam or a doorbell camera, the PL‑02934H‑M12 offers the optical performance and mechanical robustness that BOSHI Optical Technology is known for, with full compatibility with 1/4" sensors and M12 interfaces.

19mm F1.0 M22 12um AR Lens Long-wave Infrared Thermal Imaging Lens is a 13mm F1.0 LWIR thermal lens working at 8–12μm, optimized for 640×512 (12μm pitch) uncooled infrared detectors. Core Strengths: 1.Ultra-large F1.0 aperture plus ≥90% high-transmittance AR coating delivers top-tier sensitivity for long-distance faint heat source detection; 2.Extra-high relative illumination ≥86% ensures uniform frame brightness and error-free temperature measurement at image edges; 3.Minimum focus distance of 0.5m supports close-up inspection of tiny components, while infinity focusing enables long-range patrol missions; 4.IP67 front lens protection and -40℃~+80℃ wide temperature range enable all-weather outdoor deployment without extra protective housings; 5.19mm focal length with narrow 22.85° horizontal FOV magnifies distant targets for clear long-distance defect identification. Main Applications: Long-distance power grid inspection, photovoltaic hot spot detection, precision industrial equipment predictive maintenance, long-range border & factory perimeter security, railway contact line monitoring, early forest fire warning. Important Note: Noticeable barrel distortion (<-10%) makes it perfect for temperature detection and target identification, but not recommended for high-precision dimensional measurement tasks.

This F1.0 25mm long wave infrared lens is developed and supplied by ShangHai SILK Optical Technology CO., LTD. As a high-performance thermal imaging lens working within 8~12μm wavelength range, this LWIR optics is optimized for 640×512, 12μm lens thermal detectors. Featuring a large aperture of F1.0, the infrared lens delivers outstanding light gathering capacity, making it ideal for low-visibility and low-temperature monitoring scenarios. The M22×0.5 mount ensures convenient assembly onto matched thermal camera hardware. With front element IP67 ingress protection rating, the thermal camera lens supports reliable outdoor deployment. This 25mm F1.0 lens maintains high transmittance above 86% and relative illumination over 97%, together with distortion controlled below 2%. It supports focus adjustment from 2 meters to infinity, and operates steadily between -40℃ and +80℃. ShangHai SLIK Optical Technology CO., LTD strictly calibrates every infrared lens to guarantee consistent imaging quality for industrial, security and surveillance thermal devices.
