38-424 25.4mm Dia. x 75.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. With a diameter of 25.4mm and a focal length of 75.0mm, it is designed for use in the Near-Infrared (NIR) spectrum, specifically for the wavelength of 587.6nm.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's geometry includes a thickness of 1.36mm at the edge and 3.5mm at the center, with an effective focal length (EFL) of 75mm. The front surface has a radius of curvature of 38.76mm, and the back focal length (BFL) is 72.69mm.

The lens features a coating on both the front and back surfaces, specifically the EDM NIR-II STD curve. This coating is designed to enhance the lens's performance in the NIR spectrum, improving transmission and reducing reflection. The lens is designed for use in the NIR II range, specifically between 750nm and 1550nm.

This lens is a Spherical Lens, meaning it has a spherical surface, which is the simplest type of lens surface. The lens's base shape is circular, making it suitable for a wide range of applications.

The lens's status is currently in stock, and it is available for immediate purchase and use.
