The LA1353-A is a plano-convex lens from Thorlabs, featuring a spherical geometry and a circular base shape. This lens has a diameter of 75.0 mm and a thickness at the edge of 3.0 mm, while the center thickness measures 10.1 mm. The effective focal length (EFL) of this lens is 200.0 mm. The lens's front surface has a radius of curvature (R1) of 103.0 mm, and the back focal length (BFL) is 192.7 mm. The inner and outer radii are both 0.0 mm.
This lens is made of n-BK7, a type of glass manufactured by Schott. The lens is designed to work with a wavelength of 587.6 nm. The front and back surfaces of the lens are coated with "tho a bbar," a type of anti-reflection coating that enhances the lens's performance in the 350-700 nm range.
