87-917-INK 5.0mm Dia. x 25.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 87-917-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use in the visible to near-infrared spectrum, specifically between 400-1000nm. The lens has a front and back coating of edm visnir0sp2002000, which is a broadband anti-reflection coating optimized for the visible to near-infrared range.
The lens has a thickness of 1.36mm at the edge and 1.6mm at the center, with an effective focal length (EFL) of 25mm. The radius of curvature for the first surface (R1) is 12.92mm, and the back focal length (BFL) is 23.95mm. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens is inked, which is a process where a dye is applied to the edge of the lens to indicate the orientation. This is particularly useful during assembly to ensure the correct orientation of the lens. The lens is circular in base shape, adding to its versatility in various optical systems.
The item data provides a comprehensive overview of the lens, making it easier for users to determine if this lens meets their specific requirements. The lens's properties, such as its diameter, thickness, coating, and material, are all crucial factors to consider when selecting the right lens for your application.
