LC1611-A N-BK7 Plano-Concave Lens; Dia:2 in; f=-150.0 mm ARC 350-700nm

The LC1611-A is a plano-concave lens made from N-BK7 glass, a popular material for optical elements due to its excellent optical properties. This lens, sourced from Thorlabs, features a diameter of 2 inches and a focal length of -150.0 mm, making it suitable for a wide range of applications that require negative focal lengths.

The lens's geometry includes a thickness of 8.3 mm at the edge and 4 mm at the center, with an effective focal length (EFL) of -150 mm. The radius of curvature (R1) is -77.2 mm, and the back focal length (BFL) is -152.6 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. This coating is applied to both the front and back surfaces of the lens, enhancing its performance in applications that require high transmission and low reflection.

The LC1611-A is a spherical lens, a common type of lens used in various optical systems. It is available from Thorlabs, a leading vendor in the field of optical components, and is currently in stock, ensuring quick delivery for your optical system needs.
