67-519 15.0mm Dia. x 30.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-519 is a Plano-Convex lens, a type of spherical lens, with a diameter of 15.0mm and a focal length of 30.0mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens is made from n-SF5 Schott, a high-quality optical material known for its excellent transmission properties in the NIR spectrum. The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II STD curve. This coating enhances the lens' performance in the NIR II spectrum, providing improved transmission and reduced reflection.
The geometry of the lens includes a thickness of 1.52mm at the edge and 3.8mm at the center. The lens' effective focal length (EFL) is 20mm, and its radius of curvature (R1) is 13.46mm. The back focal length (BFL) is 17.74mm, and both the inner and outer radii are 0mm.
According to the vendor's website, the lens is currently in stock, making it readily available for immediate use. The lens' specifications and properties make it an ideal choice for applications that require high-quality performance in the NIR II spectrum.
