The 49-906-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 9.0mm, is designed for use in the near-infrared spectrum, specifically between 600-1050nm, as indicated by its NIR I coating. The lens has a front and back coating of edm nir-i std curve, which enhances its performance in the specified wavelength range.
The lens has a thickness of 1.56mm at the edge and 3.0mm at the center, with an effective focal length (EFL) of 15mm. The radius of curvature for the first surface (R1) is 7.75mm, and the back focal length (BFL) is 13.02mm. The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties.
The lens is inked, which is a process that adds a dye to the lens to make it easier to handle and identify. This feature is particularly useful in large-scale production environments where thousands of lenses may be in use.
The item data provided does not include information about the lens's mounting or housing, so it's assumed to be a bare lens. Users should ensure they have the necessary components to mount and use this lens in their specific application.
