This is a Plano-Convex lens, type of spherical lens, with a circular base shape, sourced from the reputable vendor, Edmund Optics. The lens has a diameter of 15.0mm and a focal length of 22.5mm, making it suitable for a variety of optical applications.
The lens is made from n-sf5 schott, a material known for its optical properties. It is designed to operate at a wavelength of 587.6nm, which is within the visible light spectrum.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, specifically the YAG-BBAR 500-1100nm, is designed to enhance the lens' performance in the 500-1100nm wavelength range. It improves the lens' transmission and reduces reflection, thereby enhancing the overall efficiency of the optical system in which it is used.
The geometry of the lens includes a thickness of 1.36mm at the edge and 3.35mm at the center. The inner and outer radii are both 0, indicating a plano-convex lens. The radius of curvature (r1) is 15.12mm, and the back focal length (bfl) is 20.5mm.
