The 88-837-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 features a front and back coating of YAG-BBAR, a type of anti-reflective coating that enhances transmission in the 500-1100nm range.
The lens has a thickness of 1.85mm at the edge and 2.7mm at the center, with an effective focal length (EFL) of 42.0mm. The radius of curvature for the first surface (R1) is 21.71mm, and the back focal length (BFL) is 40.22mm. The lens does not have an inner or outer radius.
The lens is made of n-BK7 Schott, a common optical glass with a high refractive index and low dispersion. This makes it suitable for a wide range of optical applications. The lens is inked, a process that adds a marking or identification to the lens, typically for inventory or identification purposes.
The lens is available from Edmund Optics and is currently in stock, according to the vendor's website. For more information, users can refer to the provided weblink.
