LB4941-B UV Fused Silica Bi-Convex Lens; Dia:1 in; f=100.0 mm ARC 650-1050nm
The LB4941-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 diameter of 1 inch (25.4 mm) and a focal length of 100.0 mm, making it suitable for various optical systems.
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 the lens ideal for use in environments with varying temperatures.
The LB4941-B lens features a Spherical shape, with radii of curvature of 91.4 mm for the first surface and -91.4 mm for the second surface. The lens has an effective focal length (EFL) of 100.0 mm and a back focal length (BFL) of 98.7 mm. The center thickness of the lens is 3.8 mm, while the edge thickness is 2 mm.
The lens is coated with Thorlabs BBAR coating on both the front and back surfaces, which enhances its transmission capabilities. This coating is designed to reduce surface reflections and increase the overall transmission of the lens, making it an excellent choice for applications that require high light transmission.
