This is a Plano-Convex lens, type of spherical lens, sourced from Edmund Optics. It features a circular base shape with a diameter of 9.0mm and a thickness of 1.56mm at the edge, increasing to 3.0mm at the center. The effective focal length (EFL) of this lens is 15.0mm, making it suitable for a variety of optical applications.
The lens is made from n-BK7 Schott material, a popular choice in the optical industry due to its excellent optical properties. The front and back surfaces of the lens are coated with YAG-BBAR, a type of coating that enhances the lens' performance in the wavelength range of 500-1100nm. This coating is particularly useful for applications that require high transmission and low reflectance.
The lens is inked, a process that enhances its visibility and handling during assembly and alignment. The item data indicates that this lens is in stock, making it readily available for immediate use.
