13-464 25mm Dia. CaF2 Aspheric Lens; EFL=50mm; NA=0.25 Uncoated
This is the 13-464 model from Edmund Optics, a 25mm diameter Calcium Fluoride (CaF2) Aspheric Lens with a focal length of 50mm and a numerical aperture of 0.25. The lens is uncoated, offering a high-quality, cost-effective solution for various applications.
The lens's base shape is circular, and it is made of Calcium Fluoride (CaF2) with a catalog number of mal-1963. It is designed to operate at a wavelength of 266nm. The lens's geometry includes an inner radius of 0mm, an outer radius of 0mm, a thickness at the edge of 5.09mm, and a thickness at the center of 8.5mm. The effective focal length (EFL) is 50mm, and the back focal length (BFL) is 46.26mm.
The aspheric shape of the lens is defined by the coefficients k1 (-1.758634) and k2 (0). The lens's clear aperture is 25mm, and it has no coating. This lens is a great choice for applications that require a high level of precision and clarity, such as imaging, beam shaping, and laser applications.
Please note that the lens is uncoated, which may affect its performance in certain applications, particularly those involving high-intensity light sources or extreme environmental conditions. Always consider the specific requirements of your application when choosing an optical component.
