China 2.8mm lens Manufacturers, Suppliers, Factory

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.

f1.6 4.0mm 1/2.7" M12 Starlight Lens, and all products have been tested by MTF instruments, resulting in higher consistency compared to products from other suppliers. You can rest assured to purchase standard M12 lenses from our factory.

1/2.5" 200° IPX9 12MP Fisheye Lens Can match 1/2.5 "sensor. Equipped with IR night vision function it is with 12 million pixel lens, ttl12.8mm ultra short, monitoring panoramic lens.

This M12 board lens PL-WA2.6-14 is a high-performance ultra wide angle lens engineered by ShangHai SILK Optical Technology CO., LTD for compact surveillance and embedded imaging systems. Built as a cost-effective panoramic lens solution, this F2.0 fixed lens delivers a massive 170° diagonal field of view to eliminate blind zones for home security and vehicle monitoring. Optimized exclusively for 1/2.9” image sensors, the CCTV optical lens maintains balanced edge brightness with 68.0% relative illumination and controlled chief ray angle under 21.5°, perfectly matching mainstream CMOS sensors. The compact TTL 20.0mm design enables easy integration inside miniature camera housings. ShangHai SLIK Optical Technology CO., LTD strictly controls manufacturing tolerances to guarantee consistent optical quality of this ultra wide angle lens for mass production. It serves as an ideal fisheye board lens for consumer cameras, smart doorbells, in-car vision and mini panoramic monitoring equipment.

The optical performance of our 1/6 Inch Endoscope Lens is stable, and the manufacturing materials used for the endoscopic lens meet the requirements of SGS environmental protection medical grade. Our endoscopic lens plays an important auxiliary role in medical inspection
Our endoscopic lens is used for image guidance. The endoscopic lens transmits the image reflecting the endoscopic situation of the organ. Through the monitor, it is convenient for the doctor to observe the clear and detailed intracavitary tissue. The endoscopic lens provides help for the doctor's safe operation and fine operation .

1/6 CMOS image sensors endoscope Lenses diameter M4 is made of a combination of glass and plastic, with a wide angle of 140 degrees. shanghai silk optical provides small-sized medical for 1/6, 1/7.5, 1/9,1/11,1/15, and 1/18 etc CMOS image sensors with a large field of depth, low distortion, reliable durability, and water-resistant. These tiny plastic lenses are widely used in disposable endoscopy applications.
