67-574-INK 40.0mm Dia. x 40.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-574-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 40.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 750 and 1550nm. The lens features a front and back coating of edm nir-ii std curve, providing enhanced performance within its specified wavelength range.
The lens has a thickness of 3.08mm at the edge and 6.1mm at the center, with an effective focal length (EFL) of 75mm. The radius of curvature for the first surface (R1) is 38.76mm, and the back focal length (BFL) is 70.95mm. The lens is made from n-bk7 schott, a common material for optical lenses due to its excellent optical properties.
This lens is part of a broader category of lenses known as Spherical Lenses, which are characterized by their curved surfaces. The Plano-Convex design specifically refers to a lens with one flat surface and one curved surface. This design is often used in applications where a collimated beam needs to be focused to a spot.
The 67-574-INK is currently in stock and available for purchase through the Edmund Optics website. Its detailed specifications make it an ideal choice for users seeking a high-performance lens for NIR applications.
