88-701 15.0mm Dia. x 75.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-701 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a base shape of a circle and a diameter of 15.0mm, making it suitable for a wide range of optical applications. The lens has a thickness of 1.1mm at the edge and 1.83mm at the center, providing a balanced structure for efficient light transmission.
The effective focal length (EFL) of this lens is 75.0mm, which is the distance from the lens's center to the principal focus, where light rays converge or diverge. The first radius of curvature (R1) is 38.76mm, and the back focal length (BFL) is 73.79mm. The inner and outer radii are both 0mm, indicating a uniform curvature throughout the lens.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens ideal for use in the visible light spectrum, specifically between 350-700nm. The lens is coated with EDM VIS-EXT on both the front and back, a coating that enhances its transmission capabilities in the visible light range.
