67-652 25mm Dia. x 75mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
This is a 25mm diameter, 75mm focal length double-convex lens, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics, a leading provider of optical components, and is currently in stock.
The lens is made from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. It features a standard NIR-II coating on both the front and back surfaces, ensuring optimal performance in the 750-1550nm wavelength range.
The geometry of the lens includes a thickness of 1.45mm at the edge and 3.5mm at the center. The front and back radii are 76.66mm and -76.66mm respectively, resulting in a back focal length of 73.84mm. The lens has no inner or outer radius.
This lens is a spherical lens with a circular base shape, making it suitable for a wide range of optical applications. Its double-convex design allows for efficient light gathering and focusing, making it an ideal choice for systems requiring high-quality imaging in the NIR spectrum.
