This is a Plano-Convex lens, type 88-799-INK, sourced from Edmund Optics. The lens has a base shape of a circle and is designed for use in spherical optical systems. The lens has a diameter of 6.0mm and a thickness at the edge of 0.83mm, while the center thickness is 1.6mm. The effective focal length (EFL) of the lens is 12.0mm, making it suitable for a variety of optical applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high homogeneity. The front and back surfaces of the lens are coated with YAG-BBAR, a type of coating that provides high reflectivity in the 500-1100nm wavelength range. This coating enhances the lens's performance in the visible and near-infrared regions of the spectrum.
The lens is inked, which is a process that adds a marking or identification to the lens. This can be useful for tracking and identifying the lens in a system or for quality control purposes.
