16-288 50mm Dia. S-LAH64 NIR Aspheric Lens; EFL=40mm; NA=0.63 NIR-Plus 600-1050nm

This is the 16-288 model from Edmund Optics, a high-quality 50mm diameter aspheric lens designed for use in the near-infrared (NIR) spectrum, specifically between 600 and 1050nm. The lens is made from S-LAH64 material from Ohara, a leading manufacturer of optical glass.

The lens features a high numerical aperture (NA) of 0.63, which allows for a wide angle of acceptance and increased light gathering capabilities. The effective focal length (EFL) of the lens is 40mm, making it suitable for a variety of imaging applications.

The lens has a precise aspheric shape, which helps to reduce spherical aberration and distortion, common issues in traditional spherical lenses. The inner radius of the lens is 0, while the outer radius is also 0, indicating a symmetrical design. The lens has a thickness of 4.9mm at the edge and 15.5mm at the center.

The lens is coated with Edmund Optics' NIR-Plus coating, which is specifically designed for use in the NIR spectrum. This coating helps to reduce reflection and increase transmission, improving the overall performance of the lens. The coating is applied to both the front and back surfaces of the lens.

The lens is available for purchase through the Edmund Optics website, where it is listed as being in stock. The website also provides a detailed datasheet for the lens, which includes additional specifications and technical drawings.
