LC4210-C 12.7 mm Dia. UVFS Plano-Concave Lens; EFL=-25mm 1050-1700nm
The LC4210-C is a 12.7 mm diameter Plano-Concave Spherical Lens, designed for use in the ultraviolet to near-infrared spectrum, specifically between 1050 and 1700 nanometers. This lens is sourced from Thorlabs, a leading global manufacturer of photonics equipment.
The lens features a concave shape with a center thickness of 3 mm and an effective focal length (EFL) of -25 mm, making it suitable for a variety of applications that require light convergence or divergence. The lens's inner and outer radii are both 0, indicating a plano surface on one side and a curved surface on the other.
The LC4210-C is made from UVFS material, a type of optical glass with a high transmission range in the ultraviolet spectrum. This makes it ideal for use in UV applications, such as UV curing, spectroscopy, and fluorescence microscopy.
The lens is coated with Thorlabs' Broadband Anti-Reflection (BBAR) coating on both the front and back surfaces. This coating reduces surface reflections, enhancing the lens's transmission and overall performance. The BBAR coating is designed to work across a wide range of wavelengths, from 400 to 1100 nm, making the lens versatile for use in various applications.
