67-544-INK 25.0mm Dia. x 35.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-544-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.0mm, 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 2.35mm at the edge and 3.0mm at the center. The effective focal length (EFL) of the lens is 150mm, making it suitable for a variety of optical applications. The front surface of the lens has a radius of curvature of 77.52mm, and the back focal length (BFL) is 148.02mm.
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 lens is inked, which is a process that adds a dye or pigment to the surface of the lens. This can be used for a variety of purposes, such as marking the lens for identification or enhancing its appearance.
