The 88-826-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 at a wavelength of 587.6nm. The lens has a front and back coating of YAG-BBAR, a type of anti-reflection coating that enhances transmission in the 500-1100nm range.
The lens has a thickness of 2.39mm at the edge and 3.0mm at the center, with an effective focal length (EFL) of 40.0mm. The radius of curvature for the first surface (R1) is 20.67mm, and the back focal length (BFL) is 38.02mm. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number.
The 88-826-INK is available for purchase from the Edmund Optics website, where it is currently in stock. The link to the product page is provided for convenience. This lens is a versatile and reliable option for applications that require a small, high-performance lens with anti-reflection coating.
