38-402 12.5mm Dia. x 30.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 38-402 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, has a diameter of 12.5mm and a thickness at the edge of 1.49mm, which gradually increases to a center thickness of 3.1mm. The effective focal length (EFL) of this lens is 25mm, making it suitable for various optical applications.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is particularly suitable for near-infrared (NIR) applications, as indicated by the NIR II coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the 750-1550nm wavelength range, providing superior transmission and reducing reflection.
The 38-402 lens is currently in stock and available for immediate purchase from the Edmund Optics website. With its precise specifications and high-quality construction, this lens is an excellent choice for a wide range of optical systems and applications.
