LB4553-UV 50.8 mm Dia. UVFS Double-Convex Lens; EFL=75mm 245-400nm
The LB4553-UV is a double-convex lens with a diameter of 50.8 mm, designed for use in the ultraviolet (UV) spectrum. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components. The lens features an effective focal length (EFL) of 75mm, making it suitable for a wide range of optical applications.
The lens is constructed from UVFS, a material specifically designed for use in the UV spectrum. It has a double-convex geometry, with radii of curvature of 67mm for both the front and back surfaces. The lens has a thickness of 2.5mm at the edge and 12.5mm at the center, providing robustness and stability.
The LB4553-UV is coated with THo UVFS UV BAR on both the front and back surfaces. This coating enhances its performance in the UV spectrum, ensuring high transmission and low absorption. The coating also provides protection against environmental factors, ensuring the longevity and reliability of the lens.
