This is a Plano-Convex Lens, a type of spherical lens, sourced from the renowned optical components vendor, Edmund Optics. The lens has a diameter of 12.7mm and a focal length of 31.8mm, 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 makes the lens ideal for use in systems where high image quality and low chromatic aberration are critical.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet - Broad Band Anti-Reflection, is designed to reduce reflection and increase transmission across a broad spectrum, specifically from 500nm to 1100nm. This makes the lens particularly suitable for use in systems that operate in the near-infrared region.
The lens has a thickness of 1.72mm at the edge and 3mm at the center. The inner and outer radii are 0mm, indicating a flat surface on the uncoated side of the lens.
