The 88-896-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 25.0mm and a focal length of 750.0mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens features a YAG-BBAR coating on both the front and back surfaces. YAG-BBAR, or Yttrium Aluminum Garnet Broadband Anti-Reflective coating, is a type of coating designed to reduce reflection and increase transmission over a broad range of wavelengths, specifically 500-1100nm. This makes the lens ideal for use in applications where high transmission and low reflection are required, such as in lasers, optical instruments, and imaging systems.
The lens has a center thickness of 3.2mm and an edge thickness of 3mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 750.0mm, and the back focal length (BFL) is 747.89mm.
