The LA1353-C is a Plano-Convex lens, a type of spherical lens characterized by having one flat surface and one curved surface. This lens, sourced from Thorlabs, features a base shape of a circle, with a diameter of 75.0 mm and a thickness at the edge of 3.0 mm. The center thickness is 10.1 mm, and the effective focal length (EFL) is 200.0 mm.
The lens is made of n-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The inner radius of the lens is 0 mm, and the outer radius is also 0 mm. The radius of curvature (R1) is 103 mm, and the back focal length (BFL) is 192.7 mm.
The LA1353-C is coated with tho c bbar on both the front and back surfaces. This coating is designed to provide anti-reflection properties within the wavelength range of 1050-1700 nm. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
