SWIR lens from Rising Optics
We have a range of high resolution manual focus SWIR lenses with focal lengths ranging from 12 to 100. They match the InGaAs FPA format and provide a C interface and bayonet interface. Standard SWIR lens sizes include 16mm, 25mm, 35mm and 50mm.
Our lenses offer a large field of view and low distortion (less than 2%). Our 50 and 100 focal length options are designed to work with 1024×768-17um sensors for ultra-high resolution imaging and sharp inspection lenses. These high-performance lenses are ideal for machine vision applications where accurate and detailed views are critical.

FAQ:
What Are DLC And AR Coating?
Diamond-like carbon (DLC) membrane is an amorphous carbon membrane. The membrane contains a certain number of sp3 bonds, giving it a series of excellent properties close to diamond. It has the advantages of low deposition temperature and large area deposition.
Among various hard membranes, DLC membrane can be positioned as a membrane material with high hardness and excellent wear resistance and low coefficient of friction.
AR (Anti-Reflection) membrane cannot change the absorption rate of the lens itself. It can only increase the transmittance by reducing the reflectance on both sides of the lens, which is the so-called "reflection and antireflection".
Light is an electromagnetic wave. By matching the refractive index and thickness of the AR membrane, the light produces multi-beam interference in the AR membrane-destructive interference on the upper surface and constructive interference on the lower surface.
