45-478-INK 9.0mm Dia. x 27.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-478-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 9.0mm, is designed for use within the visible to near-infrared spectrum (VIS-NIR), specifically catering to wavelengths between 400-1000nm.
The lens's geometry is characterized by its edge thickness of 1.75mm and center thickness of 2.5mm. It boasts an effective focal length (EFL) of 27.0mm, making it suitable for a variety of optical applications. The lens's front surface features a radius of curvature of 13.95mm, while the back focal length (BFL) measures 25.35mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens is coated with a VIS-NIR coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating enhances the lens's performance within the VIS-NIR spectrum.
