67-181 9.0mm Dia. x 90.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 67-181 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 9.0mm diameter and a focal length of 90.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared regions of the spectrum (400-1000nm). This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving image quality and contrast.
The lens's geometry includes a thickness edge of 1.78mm and a thickness center of 2mm. The inner radius is 0mm, and the outer radius is also 0mm. The lens's front surface has a radius of curvature (R1) of 46.51mm, and the back focal length (BFL) is 88.68mm. The effective focal length (EFL) is 90mm.
According to the vendor's website, the lens is currently in stock, making it readily available for immediate use. This lens is a versatile and high-performing optical component, ideal for applications in the visible and near-infrared regions of the spectrum.
