67-588-INK 50.0mm Dia. x 250.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm

The 67-588-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 50.0mm, 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 of the spectrum, providing superior image quality and light transmission.

The lens has a thickness of 4.86mm at the edge and 9.0mm at the center. The effective focal length (EFL) of the lens is 150mm, providing a long focal length for detailed observations. The lens's front radius of curvature (R1) is 77.52mm, and the back focal length (BFL) is 144.07mm.

The lens is made from n-bk7 schott, a high-quality optical glass that offers excellent transmission in the visible and near-infrared regions of the spectrum. This material is known for its excellent optical properties, making it a popular choice for a wide range of optical applications.

The lens is inked, which is a process that adds a layer of ink to the lens to enhance its visibility and handling. This feature is particularly useful in applications where the lens needs to be easily identified or handled, such as in laboratory settings or in optical systems where precise alignment is required.
