16-299 45mm Dia. S-LAH64 NIR Aspheric Lens; EFL=32mm; NA=0.7 SWIR-Plus 900-1700nm

The 16-299 45mm Dia. S-LAH64 NIR Aspheric Lens is a high-quality optical component designed for use in the near-infrared (NIR) spectrum, specifically between 900 and 1700nm. This lens is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their online catalog.

The lens features a circular base shape and is constructed from S-LAH64 material, a type of optical glass produced by Ohara. It has a diameter of 45mm and a thickness of 3.02mm at the edge, with a center thickness of 13.9mm. The effective focal length (EFL) of the lens is 32mm, making it suitable for a variety of optical applications.

The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, with a front diameter of 0mm. The back focal length (BFL) is 24.18mm. The lens's shape is aspheric, with a conic constant of -0.71 and a second-order aspheric coefficient of 0. The numerical aperture (NA) is 0.7, indicating a wide acceptance angle and high light-gathering capability.

The lens is coated with Edmund Optics' SWIR-Plus 900-1700nm coating on both the front and back surfaces. This coating is specifically designed to enhance the lens's performance in the NIR spectrum, ensuring optimal transmission and minimal reflection in its intended wavelength range.
