LA4663-405 25.4 mm Dia. UVFS Plano-Convex Lens; EFL=1000mm 405nm V-Coat
The LA4663-405 is a plano-convex lens with a diameter of 25.4 mm, sourced from the reputable optical components manufacturer, Thorlabs. This lens is designed for use with a wavelength of 587.6 nm and features a vacuum-deposited anti-reflection coating on both the front and back surfaces, specifically tailored for 405 nm.
The lens's geometry is characterized by its edge thickness of 2 mm and center thickness of 2.2 mm. The effective focal length (EFL) is 1003.5 mm, making it suitable for applications that require long-focal-length lenses. The lens's shape is spherical, with a radius of curvature (R1) of 460.1 mm on the curved surface. The inner and outer radii are both zero, indicating a planar surface on the opposite side.
The lens material is UVFS, which is a type of fused silica. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. The UVFS material is identified as "UVFS mal- 1965" in the item data.
