LC4252-B 25.4 mm Dia. UVFS Plano-Concave Lens; EFL=-30mm 650-1050nm
The LC4252-B is a 25.4 mm diameter Plano-Concave Spherical Lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use within the wavelength range of 650-1050nm, making it suitable for a wide range of optical applications.
The lens features a center thickness of 3mm and an effective focal length (EFL) of -30mm, indicating its concave geometry. The concave shape is further emphasized by a radius of curvature (R1) of -13.8mm on the front surface. The lens's inner and outer radii are both 0mm, suggesting a uniform curvature across the lens surface.
The lens is crafted from UVFS material, identified by the Material ID "uvfs mal- 1965". This material is known for its excellent optical properties, making it an ideal choice for various applications.
The lens is coated with a broadband anti-reflection coating, denoted as "tho b bbar" for both the front and back surfaces. This coating reduces surface reflections, thereby enhancing the overall transmission efficiency of the lens.
