The LB4453-UV is a double-convex lens with a diameter of 25.4 mm, sourced from the reputable vendor Thorlabs. This lens is specifically designed for use in the ultraviolet (UV) spectrum, with a wavelength range of 245-400 nm, making it ideal for applications such as UV microscopy, spectroscopy, and other UV-based research and industrial settings.
The lens features an effective focal length (EFL) of 500 mm, providing a high level of magnification and precision. The geometry of the lens includes a thickness of 2 mm at the edge and 2.4 mm at the center, with a base shape of a circle. The radii of curvature for the first and second surfaces are 459.7 mm and -459.7 mm, respectively, indicating a strongly converging lens.
The lens is made from UVFS, a material specifically designed for UV applications. It comes with a UV-barrier broadband anti-reflection (BBAR) coating on both the front and back surfaces, which enhances its performance in the UV range by reducing surface reflections and increasing transmission.
This lens is available for purchase directly from Thorlabs, and as of the time of data collection, it is in stock. For more detailed information, including technical drawings and specifications, please refer to the product webpage provided.
