38-435-INK 35.0mm Dia. x 70.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm

The 38-435-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 35.0mm, 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 enhances its performance in the NIR II range.

The lens has a thickness of 1.49mm at the edge and 6mm at the center, making it suitable for various optical applications. The effective focal length (EFL) of this lens is 70.0mm, and the radius of curvature (R1) is 36.18mm. The back focal length (BFL) is 66.04mm, and the lens does not have an inner or outer radius, indicating a plano surface on the incident side.

This lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens is circular in shape, adding to its versatility in optical systems. The provided weblink offers more information about the lens and its availability.
