This is a 15mm diameter, 50mm focal length double-convex lens, offered by Edmund Optics. The lens is made from n-BK7 Schott glass, a popular choice for its high transmission and low dispersion properties in the visible spectrum. The lens features a standard MgF2 coating on both the front and back surfaces, which enhances its performance by reducing reflection and increasing transmission, particularly in the 400-700nm range.
The lens has a double-convex geometry, meaning it has two spherical surfaces that curve outwards. This design provides a large numerical aperture, making it suitable for a wide range of applications, including imaging, beam shaping, and focusing. The lens's base shape is circular, and it has an effective focal length (EFL) of 45mm, a back focal length (BFL) of 44mm, and an edge thickness of 1.77mm. The center thickness is 3mm, and the inner and outer radii are 0mm.
