The 88-877-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, 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 wavelength range of 500-1100nm.
The lens's geometry is characterized by its edge thickness of 3.32mm and center thickness of 4.3mm. The effective focal length (EFL) is 100.0mm, and the radius of curvature (R1) is 51.68mm. The back focal length (BFL) is 97.13mm, and both the inner and outer radii are 0mm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. This lens is in stock, as indicated by its weblink status, making it readily available for your optical needs.
