The 88-684 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.0mm and a focal length of 100.0mm, making it a versatile choice for various optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of EDM VIS EXT, a broadband anti-reflection coating designed for use in the visible spectrum, specifically between 350-700nm. This coating significantly reduces surface reflections, enhancing the lens's overall transmission and improving its performance in bright environments or when used with high-powered light sources.
The geometry of the lens includes a thickness of 2.15mm at the edge and 2.5mm at the center. The inner and outer radii are 0, and the lens has a BFL (back focal length) of 98.35mm and an EFL (effective focal length) of 100mm. The lens's base shape is circular, adding to its versatility in various applications.
