33-375-INK 40.0mm Dia. x 100.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 33-375-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 40.0mm and a focal length of 40.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens is made from N-SF11 Schott, a high-index glass with excellent transmittance in the NIR region. The front and back surfaces of the lens are coated with EDM NIR-II STD CURVE, a specialized coating that enhances its performance in the NIR II spectrum.
The lens has a thickness of 1.5mm at the edge and 8.7mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side and a curved surface on the other. The back focal length (BFL) is 35.13mm, and the effective focal length (EFL) is 40.0mm.
The lens is in stock and available for immediate purchase from the Edmund Optics website. The provided weblink leads directly to the product page for easy access.
