67-520-INK 15.0mm Dia. x 40.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-520-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 of the spectrum, making it ideal for applications that require precise optical performance in the NIR II range.
The lens has a thickness of 1.36mm at the edge and 3.35mm at the center. The effective focal length (EFL) of the lens is 22.5mm, and the back focal length (BFL) is 20.5mm. The lens' inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on the incident side.
The lens is made from n-sf5 schott, a material known for its excellent optical properties in the NIR II spectrum. This material, combined with the lens' precise geometry and high-quality coating, makes the 67-520-INK a reliable and high-performing optical component for NIR II applications.
According to the vendor, the lens is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
