67-514 12.7mm Dia. x 50.8mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

The 67-514 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.7mm and a focal length of 50.8mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.

The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II coating. This coating is designed to enhance the lens' performance in the near-infrared spectrum, specifically between 750nm and 1550nm. This makes the lens ideal for applications that require high-quality imaging or data collection in the NIR II range.

The lens has a thickness of 1.3mm at the edge and 2.3mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 40mm, and the back focal length (BFL) is 38.48mm.
