LA1608-YAG N-BK7 Plano-Convex Lens; Dia:1 in; f=75.0 mm YAG V-Coat 532/1064nm
This is a Plano-Convex lens from Thorlabs, designed for use in a wide range of optical applications. The lens is made from N-BK7, a popular optical glass due to its excellent optical properties, high homogeneity, and low optical dispersion. The lens has a diameter of 1 inch (25.4 mm) and a focal length of 75.0 mm, making it suitable for use in systems where a long focal length is required.
The lens features a YAG V-Coat with a center wavelength of 532/1064 nm, providing high transmission and excellent durability. This coating is designed to enhance the lens's performance in laser applications, particularly those using Nd:YAG lasers. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
The lens has a spherical shape, with a radius of curvature of 38.6 mm on the convex side. The edge thickness of the lens is 2 mm, while the center thickness is 4.1 mm. The lens's effective focal length (EFL) is 75 mm, and the back focal length (BFL) is 72.02 mm. The lens does not have any inner or outer radius, indicating a uniform thickness across the lens.
