16-301 50mm Dia. N-BK7 NIR Aspheric Lens; EFL=100mm; NA=0.25 SWIR-Plus 900-1700nm
This is the 16-301 model from Edmund Optics, a high-quality NIR (Near-Infrared) Aspheric Lens. The lens, with a diameter of 50mm, is designed for use in the SWIR-Plus range, specifically between 900nm and 1700nm. It boasts a high numerical aperture (NA) of 0.25, which allows for a wide angle of incidence and increased light-gathering capability.
The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties, including low dispersion and high transmission in the NIR range. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality and resolution.
The lens features a focal length (EFL) of 100mm, which is the distance between the lens and the point where it focuses light. This makes it suitable for applications that require a moderate level of magnification. The lens also has a thickness of 3.73mm at the edge and 10mm at the center, providing structural rigidity and stability.
The lens is coated with Edmund Optics' SWIR-Plus coating, which is designed to enhance transmission and reduce reflection in the 900-1700nm range. This coating ensures optimal performance and minimal light loss, making it ideal for applications that require high-transmission lenses.
