LC1120-A N-BK7 Plano-Concave Lens; Dia:1 in; f=-100.0 mm ARC 350-700nm

The LC1120-A is a plano-concave lens made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This lens, sourced from Thorlabs, is designed with a diameter of 1 inch and a focal length of -100.0 mm, making it suitable for a wide range of applications.

The lens's geometry is characterized by a diameter of 25.4 mm, a thickness at the edge of 5.6 mm, and a center thickness of 4 mm. The effective focal length (EFL) is -100 mm, and the radius of curvature (R1) is -51.5 mm. The back focal length (BFL) is -102.6 mm, and both the inner and outer radii are 0 mm.

The lens is coated with ARC 350-700nm on both the front and back surfaces, enhancing its performance in the specified wavelength range. This anti-reflection coating reduces unwanted reflections, improving transmission and overall system efficiency.

The LC1120-A is a spherical lens, a common choice due to its ease of manufacturing and versatility. The lens type, sub-type, and base shape are all consistent with its plano-concave design.
