This is a PLCC-25.4-64.4-C laser grade plano-concave lens, featuring a 25.4 mm diameter and a center thickness of 2.9 mm. The lens is made of N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and high damage threshold. The lens's effective focal length (EFL) is -125mm, making it suitable for applications that require a concave lens.
The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a plano surface on one side and a concave surface on the other. The concave surface has a radius of curvature of -64.4 mm. This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces.
