47-902 18mm Dia. x 36mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm

The 47-902 is a Double-Convex Lens, a type of Spherical Lens, sourced from Edmund Optics. With a diameter of 18mm and a focal length of 36mm, this lens is designed to provide high-quality optical performance. The lens features a standard coating on both the front and back surfaces, specifically the "edm vis-0 std curve" coating, which is optimized for the visible light spectrum (425-675nm).

The lens's geometry includes an edge thickness of 2.55mm and a center thickness of 4.8mm. The back focal length (BFL) is 34.59mm, while the effective focal length (EFL) is 36mm. The first and second radii of curvature are 36.6mm and -36.6mm, respectively. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range.

This lens is suitable for various applications that require high-quality imaging and light transmission in the visible light spectrum. Its compact size and robust construction make it an ideal choice for integration into optical systems. Please note that the lens's performance can be influenced by the surrounding optical system and the conditions of use. Always ensure that the lens is used within its specified parameters for optimal results.
