The 88-695 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 1.52mm at the edge and 3.8mm at the center, providing a robust structure while maintaining a compact form factor.
The effective focal length (EFL) of this lens is 20.0mm, which is the distance from the lens's center to the principal point of the light beam it focuses. This EFL makes it suitable for applications requiring moderate magnification. The lens's front radius of curvature (R1) is 13.46mm, and the back focal length (BFL) is 17.74mm, contributing to its focusing capabilities.
The lens is made from n-SF5 Schott, a high-quality optical material known for its excellent transmittance and chemical resistance. This material is particularly suitable for applications in the visible light spectrum, as indicated by the VIS-EXT coating on both the front and back surfaces of the lens. This coating enhances the lens's transmission in the 350-700nm range, making it ideal for use in various optical systems.
