88-854-INK 15.0mm Dia. x 20.0mm FL; Inked; YAG-BBAR Coated Plano-Convex Lens YAG-BBAR 500-1100nm

The 88-854-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 15.0mm and a focal length of 20.0mm, making it suitable for a variety of optical applications. The lens is made from n-sf5 Schott, a high-quality optical material known for its excellent transmission properties.

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 surface reflections and increase transmission in the spectral range of 500-1100nm. This makes the lens particularly useful in applications where high transmission and low reflection are critical, such as in laser systems, biomedical imaging, and optical communication systems.

The lens has a center thickness of 3.8mm and an edge thickness of 1.52mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's base shape is circular, adding to its versatility in various optical systems.

The lens's geometry, including its diameter, thickness, and focal length, is designed to provide excellent optical performance. The lens's EFL (Effective Focal Length) is 20.0mm, and the BFL (Back Focal Length) is 17.74mm. The R1 (Radius of Curvature) is 13.46mm. These parameters contribute to the lens's high optical quality and make it a reliable choice for a wide range of applications.
