LA4725-633 25.4 mm Dia. UVFS Plano-Convex Lens; EFL=75mm 633nm V-Coat
The LA4725-633 is a Plano-Convex Spherical Lens with a diameter of 25.4 mm, designed for use in optical systems operating at a wavelength of 633 nm. This lens is sourced from Thorlabs, a leading vendor in the field of optical components. The lens features an effective focal length (EFL) of 75 mm, making it suitable for a wide range of applications that require precise focusing and imaging capabilities.
The lens is made from UVFS material, which is specifically designed for use in the ultraviolet and visible spectrum. This material offers excellent optical performance, low auto-fluorescence, and high damage threshold, making it an ideal choice for demanding optical applications. The front and back surfaces of the lens are coated with Thorlabs' V-AR-633 coating, which is designed to reduce reflection and increase transmission at the operating wavelength.
The geometry of the lens includes a thickness of 2.1 mm at the edge and 4.4 mm at the center. The lens has a plano surface on one side and a curved surface with a radius of curvature of 34.5 mm on the other. The inner and outer radii are both zero, indicating that the lens has a uniform curvature.
