38-408-INK 12.5mm Dia. x 100.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 38-408-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for use in the NIR II spectrum. This coating enhances the lens' performance in this region, providing superior transmission and reducing unwanted reflections.
The lens has a thickness of 1.19mm at the edge and 1.7mm at the center. The effective focal length (EFL) of the lens is 75mm, making it suitable for a variety of optical applications. The lens's front surface has a radius of curvature (R1) of 38.76mm, and the back focal length (BFL) is 73.88mm.
The lens is made from n-bk7 schott, a popular optical material known for its excellent optical properties and high damage threshold. This material ensures the lens delivers high-quality images with minimal distortion.
The item data also indicates that the lens is 'inked', suggesting that it may have markings or identifiers for inventory management or quality control purposes. However, the specifics of these markings are not provided in the item data.
