LC4924-UV 12.7 mm Dia. UVFS Plano-Concave Lens; EFL=-20mm 245-400nm
The LC4924-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 field of optical components. The lens features an effective focal length (EFL) of -20mm, making it suitable for a wide range of applications that require concave lenses.
The lens is made from UVFS, a material specifically designed for UV applications, with a Mal-1965 Material ID. It has a center thickness of 2mm, providing a balance between compactness and durability. The lens's geometry, including its inner and outer radii, is optimized for UV applications, particularly within the wavelength range of 245-400nm.
The LC4924-UV is coated with a UV-optimized broadband antireflection (BBAR) coating on both the front and back surfaces. This coating, designated as THo UVFS UV BBAR, reduces surface reflections and increases transmission in the UV range, enhancing the lens's performance in its intended application.
