88-875-INK 20.0mm Dia. x 70.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 88-875-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 features 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 1.59mm at the edge and 3.0mm at the center, with a focal length (EFL) of 70.0mm. The front surface of the lens has a radius of curvature (R1) of 36.18mm, and the back focal length (BFL) is 68.03mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The YAG-BBAR coating on the lens is a broadband anti-reflection coating that reduces surface reflections and increases transmission. This coating is specifically designed for use in the 500-1100nm range, making it ideal for a wide range of applications, including laser systems, optical imaging, and machine vision systems.
