47-369 25mm Dia. x 75mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 47-369 is a Double-Convex Lens, a type of Spherical Lens, sourced from Edmund Optics. This lens boasts a 25mm diameter and a focal length of 75mm, making it suitable for a variety of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating is designed to enhance the lens' performance in the visible light spectrum, specifically between 425-675nm. The coating helps to reduce surface reflections, improving the overall transmission of light through the lens.
The geometry of the lens is also noteworthy. The edge thickness measures 1.45mm, while the center thickness is 3.5mm. The lens' back focal length is 73.84mm, and the radii of curvature for the first and second surfaces are 76.66mm and -76.66mm, respectively. The lens' inner and outer radii are both zero, indicating a uniform thickness throughout.
