LA1131-YAG N-BK7 Plano-Convex Lens; Dia:1 in; f=50.0 mm YAG V-Coat 532/1064nm

This is a LA1131-YAG N-BK7 Plano-Convex Lens, a high-quality optical component sourced from Thorlabs. The lens, which has a diameter of 1 inch (25.4 mm), is designed with a focal length of 50.0 mm, making it suitable for a wide range of optical applications.

The lens is made of N-BK7, a popular glass type known for its excellent optical properties. This material, also known as Schott glass, is characterized by its low dispersion and high Abbe number, making it an ideal choice for applications that require high image quality and low chromatic aberration.

The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). The curvature of the lens is defined by a radius of 25.8 mm, which contributes to its focal length. The lens has a central thickness of 5.3 mm and an edge thickness of 2 mm, providing structural integrity and resistance to optical distortion.

The LA1131-YAG lens is coated with a YAG V-Coat, specifically designed for use at 532 nm and 1064 nm wavelengths. This coating enhances the lens's performance by reducing surface reflections and improving transmission, thereby increasing the overall efficiency of the optical system.
