LC1315-A N-BK7 Plano-Concave Lens; Dia:2 in; f=-75.0 mm ARC 350-700nm

The LC1315-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, features a diameter of 2 inches (50.8 mm) and a focal length of -75.0 mm, making it suitable for a wide range of applications.

The lens's geometry includes a thickness of 13 mm at the edge and 3.5 mm at the center, with an effective focal length (EFL) of -75 mm. The radius of curvature (R1) is -38.6 mm, and the back focal length (BFL) is -77.3 mm. The lens's inner and outer radii are both 0, indicating a flat surface on one side and a curved surface on the other.

The lens is coated with ARC 350-700nm, a broadband anti-reflection coating that reduces reflection across the visible spectrum, enhancing transmission and improving overall performance. The coating is applied to both the front and back surfaces of the lens.

This lens is a spherical lens, a common type of lens used in various optical systems. It is available from Thorlabs, a reputable vendor known for its high-quality optical components. According to the vendor's website, the lens is currently in stock, ensuring quick delivery for your optical project needs.
