The 38-571-INK is a plano-convex lens, a type of spherical lens, with a diameter of 9.0mm and a focal length of 10mm. This lens is sourced from Edmund Optics, a reputable vendor in the optical industry. The lens features a YAG-BBAR coating on both the front and back surfaces, designed to enhance performance within the wavelength range of 500-1100nm.
The lens's geometry includes a thickness of 1.28mm at the edge and 2.7mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on the opposite side of the convex surface. The lens's effective focal length (EFL) is 10mm, and the back focal length (BFL) is 8.49mm.
The lens is made from n-SF11 Schott, a high-index glass with excellent optical properties. The lens's shape is spherical, and it is designed to be used in a circular base shape. The YAG-BBAR coating on the lens is a type of anti-reflection coating that reduces surface reflections and increases transmission.
