67-495-INK 12.0mm Dia. x 18.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-495-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, 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 image quality and light transmission.
The lens has a thickness of 1.66mm at the edge and 4.5mm at the center. The effective focal length (EFL) of the lens is 15mm, making it suitable for a variety of optical applications. The lens's front surface has a radius of curvature (R1) of 7.75mm, and the back focal length (BFL) is 12.03mm.
The lens is made from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence in the NIR region. The lens is inked, which is a process that adds a marking or identification to the lens, making it easier to identify and track in an optical system.
