67-458-INK 5.0mm Dia. x 20.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-458-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. The lens features a front and back coating of edm nir-ii std curve, which enhances its performance in the NIR range.
The lens has a thickness of 1.19mm at the edge and 1.5mm at the center, with an effective focal length (EFL) of 20.0mm. The radius of curvature for the first surface (R1) is 10.34mm, and the back focal length (BFL) is 19.02mm. The lens is made of n-bk7 schott, a material known for its excellent optical properties.
The lens is inked, which is a process that adds a dye or pigment to the surface of the lens. This can be useful for marking or identifying the lens, or for absorbing stray light. The lens is circular in base shape, making it suitable for a wide range of applications.
