22-775 12.5mm Dia. Germanium Infrared Aspheric Lens; EFL=9.5mm; NA=0.65 BBAR 3-12µm

This is a high-quality aspheric lens from Edmund Optics, with the catalog number 22-775. It is designed for infrared applications, with a wavelength of 8000 nanometers. The lens is made of germanium burnett, a material known for its excellent transmission properties in the infrared spectrum.

The lens has a diameter of 12.5mm and an effective focal length of 9.5mm, making it a compact yet powerful option for your optical system. The aspheric design allows for superior image quality, reducing spherical aberration and distortion compared to traditional spherical lenses.

The lens features a high numerical aperture (NA) of 0.65, which allows for a wide angle of view and increased light gathering capability. The front and back surfaces of the lens are coated with edm arcedgermanium31, a broadband anti-reflection coating that enhances transmission and reduces surface reflections.

The lens has a thickness of 4.36mm at the edge and 5mm at the center, providing structural rigidity and resistance to deformation. The inner and outer radii are 0mm, indicating a circular shape.

This lens is available for purchase from the Edmund Optics website, and the link provided is valid and indicates that the lens is in stock. With its high-quality materials, advanced design, and excellent specifications, this lens is an excellent choice for a wide range of infrared optical applications.
