67-279 15mm Dia. UVFS Aspheric Lens; EFL=12.5mm; NA=0.6 NIR 600-1050nm
This is a high-quality aspheric lens from Edmund Optics, catalog number 67-279. It is designed for use in the near-infrared spectrum, specifically for wavelengths between 600 and 1050nm. The lens is made from UV fused silica, a material known for its excellent transparency in the UV and NIR ranges.
The lens has a diameter of 15mm and a numerical aperture (NA) of 0.6. The effective focal length (EFL) is 12.5mm, making it a medium telephoto lens. The lens features a sophisticated aspheric design, which helps to reduce spherical aberration and distortion, resulting in sharper images with improved contrast and resolution.
The lens is coated with Edmund Optics' NIR coating, which is specifically designed for use in the near-infrared spectrum. This coating helps to reduce reflection and increase transmission, improving the overall performance of the lens.
The lens has a center thickness of 9mm and an edge thickness of 2.47mm. The front and back surfaces of the lens are both coated with the same NIR coating. The lens is available for purchase directly from the Edmund Optics website, where it is currently in stock.
