LB4941 UV Fused Silica Bi-Convex Lens; Dia:1 in; f=100.0 mm Uncoated

The LB4941 UV Fused Silica Bi-Convex Lens is a high-quality optical component sourced from Thorlabs. This lens, with a diameter of 1 inch and a focal length of 100.0 mm, is designed for use in a wide range of applications that require excellent optical performance.

The lens is made of UV Fused Silica, a material known for its high transparency in the ultraviolet region, making it an ideal choice for applications that involve UV light. The lens's geometry includes a diameter of 25.4 mm, an edge thickness of 2 mm, and a center thickness of 3.8 mm. The effective focal length (EFL) is 100.0 mm, and the back focal length (BFL) is 98.7 mm. The lens's shape is spherical, with radii of curvature R1 and R2 being 91.4 mm and -91.4 mm, respectively.

The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means that the lens is less susceptible to damage from environmental factors, making it suitable for harsh environments.

According to the vendor's website, the lens is in stock, indicating its availability for immediate purchase and delivery. The website also provides further technical details and specifications, which can be useful for users who want to understand the lens's performance in more detail.
