88-691-INK 12.7mm Dia. x 44.5mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-691-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.7mm, is designed for use within the visible light spectrum, specifically optimized for wavelengths around 587.6nm. The lens has a front and back coating of edm vis ext, which enhances its performance within the specified wavelength range.
The lens's geometry is characterized by its edge thickness of 1.86mm and center thickness of 2.75mm. The effective focal length (EFL) is 44.5mm, and the radius of curvature (R1) is 23mm. The back focal length (BFL) is 42.69mm, and the lens does not have an inner or outer radius.
This lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is inked, indicating that it has been marked or labeled for identification or tracking purposes.
The weblink status is valid and in stock, ensuring immediate availability for your optical needs. This lens is an excellent choice for applications that require a compact, high-performance lens within the visible light spectrum.
