67-518-INK 15.0mm Dia. x 22.5mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm

The 67-518-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 and 1550nm.

The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for use in the NIR II spectrum. This coating enhances the lens' performance in this region, providing superior image quality and light transmission.

The lens has a thickness of 1.4mm at the edge and 4.0mm at the center. The effective focal length (EFL) of the lens is 18mm, providing a moderate level of magnification. The lens' front surface has a radius of curvature of 12.11mm, while the back surface has a radius of curvature of infinity, indicating a flat surface.

The lens is made from n-sf5 schott, a high-quality optical material known for its excellent transmission properties in the NIR II spectrum. This material ensures that the lens provides high-quality images with minimal distortion or loss of light.
