The LB4280-UV is a 6 mm diameter double-convex lens, designed for use in the ultraviolet (UV) spectrum, specifically between 245 and 400 nanometers. This lens is sourced from Thorlabs, a leading global manufacturer of photonics equipment.
The lens features an effective focal length (EFL) of 10mm, making it suitable for a variety of applications that require precise focusing or imaging in the UV range. The double-convex design, with radii of curvature of 8.8mm for both the front and back surfaces, contributes to its high optical power and excellent image quality.
The LB4280-UV is made from UVFS, a material specifically designed for UV applications. This material has a refractive index that optimizes its performance in the UV range, ensuring high transmission and minimal absorption.
The lens is coated with a UV-enhanced broadband antireflection coating, which further improves its performance in the UV range. This coating, applied to both the front and back surfaces, reduces surface reflections and increases transmission, thereby enhancing the overall optical performance of the lens.
The lens has a center thickness of 2.6mm and an edge thickness of 1.5mm, providing a robust and durable design. The lens is circular in shape, with no inner or outer radius, making it suitable for use in a wide range of optical systems.
