LB4282-UV 25.4 mm Dia. UVFS Double-Convex Lens; EFL=200mm 245-400nm

The LB4282-UV is a high-quality double-convex lens, boasting a diameter of 25.4 mm and a focal length of 200 mm, specifically designed for use in the ultraviolet spectrum, between 245-400 nm. This lens is sourced from the renowned optical component manufacturer, Thorlabs, ensuring reliability and precision.

The lens is constructed from UVFS, a material with a refractive index optimized for ultraviolet light, and has a double-convex geometry, with radii of curvature of 183.6 mm and -183.6 mm for the front and back surfaces, respectively. This geometry provides excellent focusing capabilities and a wide field of view. The lens has a central thickness of 2.9 mm and an edge thickness of 2 mm, contributing to its robustness and durability.

The LB4282-UV is coated with a broadband anti-reflection coating, specifically designed for the UVFS material and the ultraviolet spectrum. This coating, denoted as 'tho uvfs uv bbar', reduces surface reflections, enhancing transmission and improving overall system performance.

This lens is an excellent choice for various applications, including UV imaging, spectroscopy, and beam shaping. Its high-quality construction, optimized design, and broadband anti-reflection coating make it a versatile and reliable component in any UV optical system.
