LC5919-E 12.7 mm Dia. CaF2 Plano-Concave Lens; EFL=-18mm 2-5µm
The LC5919-E is a Plano-Concave Spherical Lens, boasting a 12.7 mm diameter and a center thickness of 2 mm. This lens is designed for use with a wavelength of 588 nm and features an effective focal length (EFL) of -18 mm, making it suitable for a variety of applications. The lens is crafted from Calcium Fluoride (CaF2) with the material ID "caf2 mal-1963".
The LC5919-E is coated with AR coatings on both the front and back surfaces, specifically the "tho ecaf2arc20005000" coating. This coating enhances the lens' performance by reducing reflection and increasing transmission, thereby improving overall image quality.
The lens' geometry is defined by its inner and outer radii, both of which are 0 in this case, and its concave surface with a radius of curvature (R1) of -7.8 mm. This lens is part of Thorlabs' extensive catalog, which offers a wide range of optical elements for various applications.
