67-523-INK 15.0mm Dia. x 75.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-523-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 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 1.59mm at the edge and 3.0mm at the center. The effective focal length (EFL) of the lens is 40mm, making it suitable for a variety of optical applications. The lens's front surface has a radius of curvature of 20.67mm, and the back focal length (BFL) is 38.02mm.
The lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties and versatility. This material ensures high transmission and low dispersion, making it ideal for use in the NIR II spectrum.
The lens is inked, a process that adds a dye to the lens to enhance contrast and make it easier to handle and align during assembly. This feature is particularly useful in high-precision optical systems where accurate alignment is critical.
