67-549 25.0mm Dia. x 85.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-549 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a diameter of 25.0mm and a focal length of 85.0mm, 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 of the curved surface is 25.84mm, and the lens has an effective focal length (EFL) of 50mm. The lens's thickness at the edge is 1.68mm, while its center thickness is 4.9mm.
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 provides high transmittance and excellent durability, ensuring the lens's longevity and reliability.
