LC4232-UV 12.7 mm Dia. UVFS Plano-Concave Lens; EFL=-100mm 245-400nm
The LC4232-UV is a plano-concave lens with a diameter of 12.7 mm, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use in the ultraviolet (UV) spectrum, specifically between 245 and 400 nanometers, making it an ideal choice for UV applications.
The lens features an effective focal length (EFL) of -100mm, indicating its concave shape. The negative focal length is typical of concave lenses, which diverge light rays. This property can be useful in various applications, such as beam expansion or collimation.
The LC4232-UV is made from UVFS, a material with a refractive index suitable for UV applications. The lens's geometry includes a center thickness of 3.5 mm, with the inner and outer radii being zero, indicating a plano-concave shape.
The lens is coated with a UV-optimized broadband anti-reflection (BBAR) coating on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission in the UV range.
