67-483 9.0mm Dia. x 90.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-483 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The 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 popular optical glass due to its excellent optical properties and versatility. It has a refractive index of 1.5168 at 587.6nm, which contributes to its high-performance capabilities.
The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II std curve. This coating enhances the lens's performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm, making it ideal for NIR applications.
The lens's geometry is another notable feature. It has a thickness of 1.1mm at the edge and 1.54mm at the center. The front surface has a radius of curvature of 23.26mm, while the back surface has a radius of curvature of 43.98mm. The lens's effective focal length (EFL) is 45mm, and its back focal length (BFL) is 43.98mm.
