The 38-593-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 visible light spectrum, specifically at a wavelength of 587.6nm. The lens is made from the high-quality material n-BK7 Schott, ensuring excellent optical performance.
The lens features a front and back coating of YAG-BBAR, a type of anti-reflective coating designed for use in the 500-1100nm wavelength range. This coating helps to reduce surface reflections, improving the overall transmission of light through the lens. The lens has a thickness of 1.22mm at the edge and 1.6mm at the center, with an effective focal length (EFL) of 100mm.
The lens's inner and outer radii are 0, indicating a flat surface on the lens's entrance and a curved surface on the exit. The lens's radius of curvature (R1) is 51.68mm, and its back focal length (BFL) is 98.95mm. This lens is inked, which aids in identifying the lens's orientation during use.
