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.

BOSHII 1/4” 200° M12 Fisheye Lens， Can match 1/4 "sensor. Equipped with IR night vision function it is with 2 million pixel lens, ttl11.5mm ultra short, monitoring panoramic lens.

Our4mm 4MP FullColor F1.0 blacklight Starlight M12 lens demonstrates significant advantages in stray light suppression, edge imaging sharpness and light transmittance, with higher yield and better consistency. It can still clearly capture details in low-light conditions.

This high‑performance 75mm thermal imaging lens is developed and manufactured by ShangHai SILK Optical Technology CO., LTD, optimized for 640×512, 17μm infrared detectors to deliver sharp long‑wave infrared imaging output. Featuring a large aperture F1.0 design, this F1.0 athermal lens realizes reliable optical athermalization without extra electric focusing parts, maintaining stable imaging quality within‑40℃ ~ +80℃ extreme working environment. With HD exposed‑optics coating, high transmittance up to 88% and over 96% relative illumination, this infrared lens restores uniform brightness across the whole field of view, while low 0.85% distortion minimizes image geometric deviation. The M34×0.75 mechanical mount ensures quick and stable assembly, and IP67 front‑element waterproof rating brings solid dust‑proof and moisture‑proof capability. Weighs only approx.475g, the compact‑structured thermal imaging lens suits integration into various infrared observation devices.
