The 38-364-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use in the near-infrared spectrum, specifically between 600-1050nm, as indicated by its NIR I coating.
The lens's geometry is characterized by its edge thickness of 1.19mm and center thickness of 1.7mm, with an effective focal length (EFL) of 75mm. The front surface of the lens has a radius of curvature (R1) of 38.76mm, and the back focal length (BFL) is 73.88mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties.
The lens's coating, both on the front and back surfaces, is Edmund Optics' standard NIR-I coating. This coating is designed to enhance the lens's performance in the near-infrared spectrum, ensuring optimal transmission and minimal reflection.
