LC1054-B N-BK7 Plano-Concave Lens; Dia:0.5 in; f=-25.0 mm ARC 650-1050nm
The LC1054-B is a plano-concave lens with a diameter of 0.5 inches and a focal length of -25.0 mm. This lens is sourced from Thorlabs, a leading vendor in the optical industry, and is currently in stock with valid weblinks provided for easy reference.
The lens is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties. The lens geometry includes a diameter of 12.7 mm, a thickness at the edge of 4.7 mm, and a thickness at the center of 3 mm. The effective focal length (EFL) is -25 mm, and the radius of curvature (R1) is -12.9 mm. The back focal length (BFL) is -27 mm, and both the inner and outer radii are 0 mm.
This lens is designed for use in the wavelength of 587.6 nm. It comes with a broadband anti-reflection coating (ARC) for the wavelength range of 650-1050 nm on both the front and back surfaces, ensuring high transmission and minimal reflection. The lens shape is spherical, a common choice for its ease of manufacturing and good optical performance.
