38-422-INK 25.4mm Dia. x 40.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm

The 38-422-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.4mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm. The lens features a front and back coating of edm nir-ii std curve, providing optimal performance within its specified wavelength range.

The lens has a thickness of 1.54mm at the edge and 5.9mm at the center, with an effective focal length (EFL) of 40mm. The radius of curvature for the first surface (R1) is 20.67mm, and the back focal length (BFL) is 36.11mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.

This lens is inked, indicating that it has been marked with a unique identifier for tracking and inventory purposes. Despite the ink, the lens maintains its high-quality optical performance, making it suitable for a wide range of applications within the NIR II spectrum.

The lens's geometry and material make it suitable for use in various applications, including biomedical imaging, optical communication, and spectral analysis. The edm nir-ii std curve coating ensures minimal reflection and high transmission, making it ideal for use in systems where maximum light transmission is required.
