This product is a 25mm diameter, 400mm focal length plano-convex lens, offered by Edmund Optics. The lens is designed for visible light applications, specifically within the wavelength range of 425-675nm, and features a standard antireflection coating on both the front and back surfaces.
The lens's geometry includes a 2.01mm edge thickness and a 2.44mm center thickness. The front surface has a radius of curvature of 183.39mm, and the back focal length is 398.33mm. The lens is made of fused silica (mal-1965), ensuring high optical quality and resistance to thermal shock.
The coating on this lens is Edmund Optics' standard visible coating (edm vis-0 std curve), which is designed to minimize surface reflections and improve transmission in the visible spectrum. This coating is particularly useful for applications that require high light transmission and low stray light, such as imaging systems, beam shaping, and laser applications.
