LC4918-UV 12.7 mm Dia. UVFS Plano-Concave Lens; EFL=-200mm 245-400nm
The LC4918-UV is a plano-concave lens with a diameter of 12.7 mm, designed for use in the ultraviolet (UV) spectrum. This lens is sourced from Thorlabs, a leading vendor in the optical components industry. The lens features an effective focal length (EFL) of -200mm, making it suitable for a wide range of applications that require negative focal lengths.
The lens is made from UVFS, a material specifically designed for UV applications, with a wavelength of 588nm. It is coated with a UV-optimized broadband antireflection coating (UV BARR), which enhances its performance in the UV range (245-400nm). This coating reduces surface reflections, thereby improving transmission and overall system efficiency.
The LC4918-UV has a spherical shape, with a center thickness of 4mm. The inner and outer radii are 0mm, indicating a plano-concave design. This design is often used in beam expanding or reducing applications.
The lens is currently in stock and available for immediate purchase. For more information, including technical specifications and pricing, please refer to the vendor's website using the provided weblink.
