88-819 9.0mm Dia. x 72.0mm FL; YAG-BBAR Coated Plano-Convex Lens YAG-BBAR 500-1100nm

The 88-819 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 9.0mm and a focal length of 72.0mm, making it suitable for a wide range of optical applications.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures that the lens provides clear, distortion-free images, making it ideal for use in imaging systems, beam shaping, and other applications where high-quality optical performance is required.

The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet - Broad Band Anti-Reflection, is designed to reduce reflection and increase transmission across a broad spectrum of wavelengths, from 500nm to 1100nm. This makes the lens particularly suitable for use in multi-spectral or broadband optical systems.

The geometry of the lens is also noteworthy. The edge thickness is 1.73mm, while the center thickness is 2.0mm. The lens's inner radius is 0mm, and the outer radius is also 0mm. These geometric properties, combined with the lens's material and coating, contribute to its excellent optical performance.
