63-685 30mm Dia. x 60mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm

The 63-685 is a high-quality double-convex lens, boasting a 30mm diameter and a focal length of 60mm. This lens is sourced from the reputable vendor, Edmund Optics, and is readily available for your optical system requirements.

The lens is crafted from the renowned N-BK7 glass from Schott, a material known for its excellent optical properties and versatility. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature R1 and R2 measured at 61.15mm and -61.15mm, respectively. This geometry results in a back focal length of 58.33mm.

The lens's edge thickness is 1.26mm, while the center thickness is 5mm, providing robustness and durability. The effective focal length (EFL) of the lens is 60mm, making it suitable for a wide range of applications.

The 63-685 lens is coated with the EDM VIS-NIR 0SP 200-2000 coating on both the front and back surfaces. This coating enhances the lens's performance in the visible (VIS) and near-infrared (NIR) spectrum, specifically between 400nm and 1000nm. The coating ensures high transmission, low reflectance, and improved durability, making this lens an excellent choice for various applications.
