47-373 25mm Dia. x 175mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
This is a 25mm diameter, 175mm focal length double-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens is designed for the visible light spectrum, specifically catering to the 425-675nm range.
The lens features a double-convex geometry, characterized by its base shape being circular and both surfaces curving outwards. This design is particularly beneficial for applications requiring a wide field of view and minimal distortion. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a symmetrical design.
The lens's geometry also includes a 2.33mm thickness at the edge and a 3.2mm thickness at the center. The effective focal length (EFL) is 175mm, and the back focal length (BFL) is 173.94mm. The radii of curvature for the first and second surfaces are 180.4mm and -180.4mm, respectively.
The lens is made of N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. This makes the lens suitable for a wide range of applications, including imaging, beam shaping, and laser systems.
The lens features a standard VIS 0deg coating on both the front and back surfaces. This coating is designed to enhance transmission in the visible spectrum while providing protection against environmental factors such as dust and moisture.
