The 88-617 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 3mm, making it compact and versatile for various applications. The lens's thickness at the edge is 1.41mm, while its center thickness is 1.8mm, providing a balanced structure for light transmission.
The effective focal length (EFL) of this lens is 6mm, which is the distance from the lens's center to the principal point of the light beam it focuses. This EFL makes the lens suitable for applications requiring a moderate level of magnification. The front radius of curvature (R1) is 3.1mm, and the back focal length (BFL) is 4.81mm, contributing to the lens's overall optical performance.
The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. It is coated with EDM VIS EXT on both the front and back, a coating designed for use in the visible spectrum (350-700nm). This coating enhances the lens's transmission and reduces reflection, making it more efficient for light transmission.
