BICC-25.4/50.0C 25.4 mm Dia. x -48 mm FL; Uncoated; Double-Concave Lens

This is a Spherical Lens (Concave-Concave) type optical component with a diameter of 25.4 mm, sourced from Laser Components. The lens is uncoated and features a double-concave design, making it suitable for a variety of applications where beam convergence is required.

The lens has a center thickness of 2 mm and an edge thickness of 5.3 mm. The effective focal length (EFL) is -48 mm, indicating that it will cause incoming parallel rays to converge at a point 48 mm away from the lens. The first radius of curvature (R1) is -50 mm, while the second radius of curvature (R2) is 50 mm, which are the curvatures of the two surfaces of the lens.

The lens is made of n-BK7 Schott material, a common and high-quality optical glass. It is designed to work with a wavelength of 633 nm. The lens is circular in base shape and has no inner or outer radius, indicating that it is a simple double-concave lens.

Please note that the lens is uncoated, which means it does not have any anti-reflective or other coatings. This may affect its performance in high-intensity or high-precision applications. However, it can be a cost-effective solution for applications where such coatings are not necessary.
