LA4102-633 25.4 mm Dia. UVFS Plano-Convex Lens; EFL=200mm 633nm V-Coat

The LA4102-633 is a Plano-Convex Spherical Lens with a diameter of 25.4 mm, designed for use with a wavelength of 587.6 nm. This lens is sourced from Thorlabs, a reputable vendor known for their high-quality optical components.

The lens features an effective focal length (EFL) of 200 mm, making it suitable for applications that require a longer focal length. The Plano-Convex design, where one side is flat and the other is curved, is a common choice for beam shaping and focusing applications.

The lens is made from UVFS material, which is a type of optical glass. The specific UVFS material used in this lens is identified as "UVFS mal- 1965". This material has excellent transmission properties in the ultraviolet, visible, and near-infrared regions of the spectrum.

The LA4102-633 is coated with Thorlabs' V-AR-633 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission at the specified 633 nm wavelength. The edge thickness of the lens is 2 mm, while the center thickness is 2.9 mm, providing a good balance between optical performance and mechanical robustness.
