The 88-670-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 10.0mm, is designed for use in the visible light spectrum, specifically between 350-700nm, as indicated by its VIS-EXT coating. The lens has a focal length of 100.0mm, making it suitable for a variety of optical applications.
The lens's geometry includes a thickness of 2.76mm at the edge and 3.0mm at the center. The front surface has a radius of curvature of 51.68mm, and the back focal length is 98.02mm. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The VIS-EXT coating on both the front and back surfaces enhances the lens's performance in the visible light spectrum. This coating reduces reflection and increases transmission, making the lens more efficient in transmitting light. The coating also provides environmental protection, reducing the lens's susceptibility to damage from dirt, dust, and other environmental factors.
