16-300 50mm Dia. S-LAH64 NIR Aspheric Lens; EFL=40mm; NA=0.63 SWIR-Plus 900-1700nm

The 16-300 is a high-performance NIR (Near-Infrared) Aspheric Lens, manufactured by Edmund Optics, featuring a 50mm diameter and a numerical aperture (NA) of 0.63. This lens is designed for use within the wavelength range of 900-1700nm, making it suitable for a wide range of applications within the SWIR (Shortwave Infrared) spectrum.

The lens is constructed from S-LAH64, a high-quality optical glass from Ohara, which is renowned for its excellent transmittance and low autofluorescence properties in the NIR region. The lens features a focal length (EFL) of 40mm, providing a good balance between field of view and image magnification.

The 16-300 lens boasts an aspheric surface on both sides, which helps to reduce spherical aberration and distortion, thereby improving image quality. The lens has a center thickness of 15.5mm and an edge thickness of 4.9mm, contributing to its robustness and durability.

The lens is coated with Edmund Optics' proprietary SWIR-Plus coating, which is specifically designed for the 900-1700nm range. This coating enhances the lens's transmission efficiency and provides excellent protection against environmental factors, ensuring the lens maintains its performance over time.
