88-917-INK 40.0mm Dia. x 400.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm

The 88-917-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 40.0mm and a focal length of 400.0mm, making it suitable for a wide range of optical applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number.

The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet Broadband Anti-Reflective coating, is designed to reduce surface reflections and increase transmission across a broad spectrum, specifically from 500 to 1100nm. This makes the lens ideal for use in applications such as laser systems, beam shaping, and imaging systems that operate within this wavelength range.

The geometry of the lens includes a thickness of 4.03mm at the edge and 5.0mm at the center. The inner and outer radii are both 0mm, indicating a flat inner surface and a curved outer surface. The lens's base shape is circular, and its shape is spherical, which is common in Plano-Convex lenses.

The lens's coating status is "inked," which means that the coating information has been inscribed on the lens itself for easy identification. This is particularly useful in multi-lens systems where different lenses need to be identified quickly and accurately.
