75mm F1.0 10MP M34 17um Lens Long-wave Infrared Thermal Imaging Lens is a high-end uncooled infrared thermal imaging telephoto lens with outstanding overall performance.

Our F1.0 darklight lens 4mm 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 thermal imaging lens is developed and manufactured by ShangHai SILK Optical Technology CO., LTD, tailored for uncooled long‑wave infrared thermal imaging devices. Featuring 50mm focal length and bright F1.0 large aperture, this infrared lens delivers outstanding light-gathering capability for low‑light thermal detection scenarios. It matches 640×512,12μm infrared detectors, working within classic 8‑12μm long‑wave infrared spectral band.

This high‑performance 35mm thermal imaging lens is developed and manufactured by ShangHai SILK Optical Technology CO., LTD, tailored for long‑wave infrared thermal imaging devices working within 8‑12μm spectral band. Boasting a large F1.0 aperture, this infrared lens delivers outstanding light‑gathering capability to secure clear thermal imaging output under low‑light and complex ambient conditions. Compatible with 640×512, 12μm uncooled infrared detectors, the thermal imaging lens supports 2m‑infinity focus range to adapt to both near‑distance observation and long‑range monitoring scenarios. Front element reaches IP67 ingress protection rating, enabling stable operation in harsh outdoor environments. With high transmittance above 92% and low distortion performance, this optical component guarantees uniform image quality across the whole field of view.

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.
