38-591-INK 12.5mm Dia. x 75.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm

The 38-591-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.5mm and a focal length of 75.0mm, making it suitable for a variety of optical applications. The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.

The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet Broadband Anti-Reflection, is designed to reduce reflection and increase transmission across a broad spectrum, specifically from 500 to 1100nm. This makes the lens particularly useful in applications that require high transmission and low reflection, such as laser systems, imaging systems, and optical metrology.

The lens has a thickness of 1.19mm at the edge and 1.7mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The back focal length (BFL) is 73.88mm, and the effective focal length (EFL) is 75mm.

The item data also indicates that this lens is 'inked', suggesting that it may be easily identifiable or labeled for inventory management or other purposes. This lens is currently in stock, according to the vendor's website, making it a readily available option for your optical needs.
