LB4030-B UV Fused Silica Bi-Convex Lens; Dia:1 in; f=40.0 mm ARC 650-1050nm
The LB4030-B UV Fused Silica Bi-Convex Lens is a high-quality optical component designed for use in a wide range of applications. This lens, sourced from Thorlabs, features a bi-convex design with a diameter of 1 inch (25.4 mm) and a focal length of 40.0 mm.
The lens is made from UV Fused Silica, a material known for its excellent optical properties, including high transparency across a broad spectrum (650-1050 nm) and a low coefficient of thermal expansion. This makes it an ideal choice for applications that require high precision and stability over a wide temperature range.
The LB4030-B lens features anti-reflection coatings on both the front and back surfaces. These coatings, designated as 'tho b bbar', are specifically designed to reduce surface reflections and increase transmission in the 650-1050 nm range. This results in improved image quality and higher overall system efficiency.
The lens has a center thickness of 6.7 mm and an edge thickness of 1.8 mm, providing a robust and durable design. The inner and outer radii are 0 mm, indicating a spherical shape. The effective focal length (EFL) is 40 mm, and the back focal length (BFL) is 37.6 mm.
