67-568-INK 30.0mm Dia. x 40.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-568-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 30.0mm, 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 image quality and light transmission.
The lens has a thickness of 2.21mm at the edge and 4.0mm at the center. The effective focal length (EFL) of the lens is 88.9mm, and the back focal length (BFL) is 86.26mm. The lens's inner and outer radii are 0mm, indicating a plano surface on the incident side.
The lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. This material is known for its low dispersion and high Abbe number, making it ideal for use in a wide range of optical applications.
