13mm F1.0 M22 12um HD 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 + ≥86% high transmittance AR coating greatly boosts weak heat source detection sensitivity; 2.Excellent imaging uniformity (≥75% relative illumination) and low distortion (≤-1.5%) ensure accurate thermal measurement without edge darkening or geometric deviation; 3.Front lens IP67 waterproof/dustproof rating and -40℃~+80℃ wide temperature range support all-weather outdoor deployment without extra protective housings; 3.1m to infinity continuous focus covers both close-range equipment inspection and long-distance surveillance; standard M20×0.5 mount ensures broad compatibility with mainstream infrared camera cores. Main Applications: Power grid inspection, perimeter & border security, industrial predictive maintenance, rail/vehicle thermal monitoring, forest fire prevention, and emergency search & rescue. Competitive Edge: Outperforms conventional F1.4/F1.8 13mm IR lenses with superior light throughput, native IP67 protection, precise measurement performance and extreme environment adaptability.

This compact machine vision lens is manufactured by ShangHai SILK Optical Technology CO., LTD, optimized for 1/4” sensor with 2592*1944 resolution. Built with reliable optical layout, this mini board lens delivers steady imaging performance with 3.05mm focal length and F5.0 aperture. It supports a 4.8mm image circle and 72‑degree diagonal FOV, meeting the wide‑view requirement of compact imaging modules. The low distortion lens design keeps TV distortion below 1.5%, together with 650nm IRCF wavelength to filter unwanted infrared interference. Ultra‑short TTL at 3.6mm makes it fit for space‑constrained device integration. ShangHai SILK Optical Technology CO., LTD carries out strict optical inspection for each unit, ensuring consistent batch quality for mass‑production projects. This cost‑effective M5.5 mount optical component is ideal for small‑size embedded camera systems across multiple consumer and industrial scenarios.
