LA1805-633 N-BK7 Plano-Convex Lens; Dia:1 in; f=30.0 mm 633nm V-Coat
The LA1805-633 is a Plano-Convex lens offered by Thorlabs, a leading global manufacturer of photonics equipment. This lens is designed for use with a wavelength of 587.6 nm and features a V-coat on both the front and back surfaces.
The lens is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and versatility. The lens has a diameter of 1 inch (25.4 mm) and a thickness that varies from 2 mm at the edge to 8.6 mm at the center.
The lens's geometry includes a 15.5 mm radius of curvature on the convex side and a back focal length of 24.19 mm. The effective focal length (EFL) is 30 mm, making it suitable for a wide range of optical applications.
The V-coat on both surfaces of the lens is designed to enhance its performance at the specified wavelength. This coating reduces reflection and increases transmission, improving the overall efficiency of the optical system in which the lens is used.
