This is a 34-195 double-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens boasts a 25mm diameter and a focal length of 200mm, making it suitable for a wide range of optical applications.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material makes the lens an ideal choice for applications that require high image quality and precise light control.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet Broadband Anti-Reflective, is designed to reduce surface reflections and increase transmission across the 500-1100nm wavelength range. This makes the lens particularly suitable for applications that involve a broad spectrum of light, such as infrared or visible light systems.
The geometry of the lens includes a thickness of 4.24mm at the edge and 5mm at the center. The radii of curvature are 205.865mm for the first surface and -205.865mm for the second surface, resulting in a back focal length of 198.35mm. The lens's base shape is circular, and its shape is spherical.
