LA4184-405 25.4 mm Dia. UVFS Plano-Convex Lens; EFL=500mm 405nm V-Coat
The LA4184-405 is a plano-convex spherical lens with a diameter of 25.4 mm, making it suitable for a wide range of optical applications. This lens, sourced from Thorlabs, features an effective focal length (EFL) of 501.8 mm, which is ideal for focusing or collimating light at the specified wavelength. The lens's geometry includes a 2 mm thickness at the edge and a 2.4 mm thickness at the center, providing a robust structure for various optical setups.
The lens is made from UVFS material with the Mal-1965 ID, which is known for its excellent optical properties in the ultraviolet region. The front and back surfaces of the lens are coated with Thorlabs' V-AR-405 coating, designed to reduce reflection and increase transmission at the 405 nm wavelength. This coating ensures optimal performance in UV applications, making the LA4184-405 an excellent choice for users working with this specific wavelength.
