67-573 30.0mm Dia. x 120.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-573 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a diameter of 30.0mm and a focal length of 120.0mm, 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 high Abbe number. This material ensures high transmittance and low dispersion, making it ideal for use in the visible and near-infrared spectrum.
The lens features a plano-convex geometry, meaning one side is flat while the other is curved. The radius of curvature for the curved side is 31.01mm, and the lens has an effective focal length (EFL) of 60mm. The lens's thickness at the edge is 2.13mm, while the center thickness is 6mm.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the near-infrared region, specifically between 750nm and 1550nm. The coating ensures high transmittance and reduces reflection, thereby improving the overall efficiency and quality of the optical system.
