The 38-594-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.7mm and a focal length of 20mm, making it suitable for a wide range of optical applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
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 coating, is designed to reduce surface reflections and increase transmission across a broad spectrum, specifically from 500nm to 1100nm. This makes the lens ideal for use in systems that operate within this wavelength range.
The lens has a thickness of 1.62mm at the edge and 3.8mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a flat surface on the uncoated side. The radius of curvature of the coated surface is 10.34mm, and the back focal length is 17.49mm.
