38-285-INK 12.5mm Dia. x 15mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
This is a Plano-Convex lens, type 38-285-INK, sourced from Edmund Optics. The lens has a base shape of a circle and is designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm. The lens is made from n-sf11 Schott material, ensuring high-quality performance.
The lens has a diameter of 12.5mm and a thickness at the edge of 1.3mm, while the center thickness is 3.1mm. The effective focal length (EFL) of the lens is 15mm, and the radius of curvature (R1) is 11.77mm. The back focal length (BFL) is 13.26mm, and both the inner and outer radii are 0mm.
The lens features a standard Vis-0 coating on both the front and back, which is a broadband anti-reflection coating designed for use within the visible spectrum (425-675nm). This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The lens is inked, indicating that it has been marked with a unique identifier for tracking and inventory purposes. The 'VIS 0deg' notation suggests that the lens is designed for use with light that is perpendicular (0 degrees) to the lens surface.
