22-776 12.5mm Dia. Germanium Infrared Aspheric Lens; EFL=12.5mm; NA=0.5 BBAR 3-12µm
This is a high-quality 22-776 12.5mm Dia. Germanium Infrared Aspheric Lens, designed and manufactured by Edmund Optics. The lens is specifically engineered for infrared applications, with a wavelength of 8000 nanometers.
The lens features a base shape of a circle, with a diameter of 12.5 millimeters and a thickness of 2.5 millimeters at the edge. The effective focal length (EFL) is 12.5 millimeters, and the back focal length (BFL) is 11.75 millimeters. The lens has a numerical aperture (NA) of 0.5, which is ideal for capturing and transmitting light.
The lens is made of Germanium burnett material, which is known for its excellent transmission properties in the infrared region. The lens also features an aspheric shape, which helps to reduce spherical aberration and improve image quality.
The lens is coated with BBAR 3-12µm, which stands for Broadband Anti-Reflection coating for 3 to 12 micrometers. This coating helps to reduce reflection and increase transmission, enhancing the performance of the lens in infrared applications.
The lens is currently in stock and available for purchase. For more information, please refer to the weblink provided.
