LA1908-633 N-BK7 Plano-Convex Lens; Dia:1 in; f=500.0 mm 633nm V-Coat

The LA1908-633 is a Plano-Convex lens, part of the extensive catalog of optical elements offered by Thorlabs. This lens, with a diameter of 1 inch, is designed for use with a focal length of 500.0 mm at a wavelength of 633 nm. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility.

The lens's geometry is characterized by a convex surface with a radius of curvature of 257.5 mm, and an edge thickness of 2 mm, which increases slightly towards the center to 2.3 mm. The lens's effective focal length (EFL) is 500 mm, and the back focal length (BFL) is 496.81 mm. The lens's design is spherical, a common choice for its simplicity and cost-effectiveness.

The LA1908-633 is coated with a V-coat, specifically designed for the 633 nm wavelength. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission. The coating is applied to both the front and back surfaces of the lens.
