LB4265-UV 25.4 mm Dia. UVFS Double-Convex Lens; EFL=150mm 245-400nm
The LB4265-UV is a high-quality spherical lens from Thorlabs, designed with a double-convex geometry and a circular base shape. This lens boasts a diameter of 25.4 mm and a center thickness of 3.2 mm, making it a robust and durable choice for various optical applications. The lens's edge thickness is 2 mm, contributing to its structural integrity.
The lens's effective focal length (EFL) is 150 mm, which is a versatile length for many optical systems. The first radius of curvature (R1) is 137.5 mm, while the second radius of curvature (R2) is -137.5 mm, indicating the lens's double-convex nature. The inner and outer radii are both 0, suggesting a uniform curvature throughout the lens.
This lens is made from UVFS, a material with the material ID "uvfs mal- 1965". It is specifically designed for use in the ultraviolet (UV) spectrum, with a wavelength of 588 nm. The lens is coated with THo UVFS UV BAR on both the front and back surfaces, enhancing its performance in UV applications.
