The 45-102 is a double-convex lens with a diameter of 15mm and a focal length of 22.5mm. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical elements. The lens is made from n-SF11 Schott, a material with excellent optical properties, ensuring high-performance imaging and light transmission.
The lens features a standard MgF2 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission in the 400-700nm wavelength range, making it ideal for a wide range of applications, including but not limited to, visible light imaging and spectroscopy.
The geometry of the lens includes a thickness of 2.54mm at the edge and 4.2mm at the center. The effective focal length (EFL) is 22.5mm, and the back focal length (BFL) is 21.29mm. The first and second radii of curvature are 34.36mm and -34.36mm, respectively. The lens has a circular base shape, and its spherical shape ensures excellent imaging quality over a wide field of view.
