38-388 6.0mm Dia. x 25mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

This is a 6.0mm diameter by 25mm focal length plano-convex lens, specifically designed for use in the near-infrared (NIR) spectrum, covering the wavelength range of 750-1550nm. The lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.

The lens is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications. The lens features a plano-convex geometry, where one side is flat, and the other side is curved, with a radius of curvature of 12.4mm. This geometry is often used to focus or collimate light beams.

The lens has an edge thickness of 1.13mm and a center thickness of 1.5mm, providing robustness and durability. The effective focal length (EFL) of the lens is 24mm, which is the distance from the lens's center to the focal point. The back focal length (BFL) is 23.01mm, which is the distance from the lens's rear surface to the focal point.

The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the NIR spectrum, improving transmission and reducing reflection. The coating curve is not specified, but it is a standard curve optimized for NIR-II applications.
