The 88-841-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm. The lens has a front and back coating of YAG-BBAR, which is optimized for the 500-1100nm range, enhancing its performance and durability.
The lens's geometry is characterized by its edge thickness of 1.91mm and center thickness of 2.4mm. It has an effective focal length (EFL) of 72.0mm and a back focal length (BFL) of 70.42mm. The inner and outer radii are 0mm, indicating a plano surface on the non-refracting side.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. This lens is inked, a process that adds a layer of ink to the edge of the lens to protect it during handling and storage.
