The LC1060-B is a plano-concave lens with a diameter of 0.5 inches and a focal length of -30.0 mm. This lens is sourced from Thorlabs, a leading vendor in the optical industry, and is currently in stock. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, and is manufactured by Schott, a renowned glass manufacturer.
The lens's geometry includes a diameter of 12.7 mm, a thickness at the edge of 4.4 mm, and a thickness at the center of 3 mm. The effective focal length (EFL) is -30 mm, and the radius of curvature (R1) is -15.4 mm. The back focal length (BFL) is -32 mm, and both the inner and outer radii are 0 mm.
The LC1060-B is coated with a broadband anti-reflection coating, specifically the Thorlabs BBAR coating, which is designed to reduce reflection across the 650-1050 nm wavelength range. This coating is applied to both the front and back surfaces of the lens.
