67-533-INK 20.0mm Dia. x 30.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-533-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically between 750-1550nm.
The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for NIR II applications. This coating enhances the lens' performance in the NIR II spectrum, providing superior image quality and light transmission.
The lens has a thickness of 1.9mm at the edge and 3.0mm at the center. The effective focal length (EFL) of the lens is 72mm, making it suitable for a wide range of optical applications. The lens's front surface has a radius of curvature (R1) of 37.22mm, and the back focal length (BFL) is 70.05mm.
The lens is made from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence in the NIR spectrum. This makes the lens ideal for use in applications such as bio-imaging, night vision, and spectral analysis.
