88-640-INK 6.0mm Dia. x 12.0mm FL; VIS-EXT; Inked; Plano-Convex Lens
The 88-640-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 6.0mm, 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 edm vis ext, which is a type of anti-reflective coating that enhances transmission in the visible spectrum.
The lens has a thickness of 0.83mm at the edge and 1.6mm at the center, with an effective focal length (EFL) of 12mm. The radius of curvature for the first surface (R1) is 6.2mm, and the back focal length (BFL) is 10.94mm. The lens is made of n-bk7 schott, a popular optical glass known for its excellent transparency and low dispersion.
The lens is inked, which is a process that adds a dye or pigment to the surface of the lens. This can be used for marking or labeling the lens, or for adjusting the lens's performance in certain wavelengths. The lens is circular in base shape, making it suitable for a wide range of optical applications.
The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website at https://www.edmundoptics.com/f/vis-ext-coated-plano-convex-pcx-lenses/14893/.
