33-357 12.0mm Dia. x 36.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, sourced from Edmund Optics, designed for use in the Near-Infrared (NIR) spectrum, specifically for wavelengths between 750nm and 1550nm. The lens has a circular base shape with a diameter of 12.0mm and a focal length of 36.0mm, making it suitable for a variety of optical applications.
The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high Abbe number. The lens's geometry includes a thickness of 1.25mm at the edge and 2.8mm at the center, with an effective focal length (EFL) of 24mm. The front surface has a radius of curvature of 12.42mm, and the back focal length (BFL) is 22.15mm.
The lens features a standard NIR-II coating on both the front and back surfaces, providing improved transmission and reduced reflection in the NIR spectrum. This coating is part of Edmund Optics' standard curve, ensuring consistent performance across similar products.
