This F1.0 19mm Infrared Thermal Lens developed by BOSHI Optical Technology is a high‑performance optical component tailored for long‑wave infrared thermal imaging systems that operate within the 8‑12μm wavelength band. This 19mm Infrared Lens supports 640×512,12μm infrared detectors, and strikes a fine balance between moderate horizontal field of view and remarkable light gathering capability. Manufactured by BOSHI Optical Technology, this Long Wave Infrared Lens applies AR Coating over all exposed optical surfaces and delivers IP67 front‑element waterproof construction to cope with complicated outdoor harsh conditions. It features adjustable focus covering 0.5 metre to infinity and maintains steady optical performance across ‑40℃ to +80℃, bringing satisfactory transmittance and relative illumination output. It acts as dependable optical hardware for industrial monitoring, perimeter security as well as temperature measurement thermal cameras.

1/3.2” 210° M12 Fisheye Lens， Can match 1/3.2 "sensor. Equipped with IR night vision function it is with 5 million pixel lens, ttl14.84 ultra short, monitoring panoramic lens.

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.

Developed and manufactured by BOSHI Optical Technology, this high‑performance 35mm thermal imaging lens targets long wave infrared thermal imaging devices operating within 8‑12μm spectral band. The thermal imaging lens adopts F1.0 large aperture design to achieve outstanding light gathering capacity, which can generate clear thermal imaging output under low‑light and complex ambient conditions. It provides full compatibility with 640×512 12μm uncooled infrared detectors. Its focus range covers 2m to infinity to support near‑distance observation and long‑range monitoring. The front element achieves IP67 ingress protection rating to sustain stable operation in tough outdoor conditions. With transmittance maintained above 92 percent and low distortion feature, this optical component delivers consistent image quality for industrial monitoring and perimeter security thermal vision systems.
