67-562 25.4mm Dia. x 50.8mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-562 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 25.4mm and a focal length of 50.8mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.
The lens features a plano-convex geometry, meaning one side is flat (plano) while the other side is curved (convex). The curvature of the convex side is defined by a radius of 387.6mm. The lens has an edge thickness of 3mm and a center thickness of 3.2mm, providing structural integrity and minimal distortion.
The 67-562 lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is specifically designed for the near-infrared (NIR) spectrum, covering the wavelength range of 750-1550nm. The coating enhances the lens's performance in the NIR region, reducing reflection and increasing transmission, thereby improving overall system efficiency.
