SLB-10-40NM 10.0 mm Dia. x -40.0 mm FL; Coated; Plano-Concave Lens 400-700nm

The SLB-10-40NM is a plano-concave lens with a diameter of 10.0 mm and a focal length of -40.0 mm, specifically designed for use within the wavelength range of 400-700nm. This lens is sourced from OptoSigma, a renowned vendor known for their high-quality optical elements.

The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The plano-concave geometry of the lens, where one surface is flat and the other is curved, is ideal for a variety of applications, particularly where light needs to be diverged or focused.

The lens features a front and back coating of opt m, which enhances its performance by reducing surface reflections and increasing transmission. The center thickness of the lens is 2.0 mm, while the edge thickness is 2.6 mm, providing a robust structure that can withstand typical handling and usage.

The lens has an inner radius of 0 mm and an outer radius of 0 mm, indicating a simple, straightforward design. The effective focal length (EFL) is -40.3 mm, and the radius of curvature (R1) is -20.76 mm. The back focal length (BFL) is -41.3 mm.
