67-497 12.0mm Dia. x 24.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type 67-497, with a diameter of 12.0mm and a focal length of 24.0mm. The lens is sourced from Edmund Optics, a renowned vendor in the optical industry. It is specifically designed for use in the Near-Infrared II (NIR II) spectrum, covering a wavelength range of 750-1550nm.
The lens is made from n-SF5 Schott, a high-quality optical material known for its excellent transmission properties in the NIR region. The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II STD curve. This coating enhances the lens' performance in the NIR II spectrum, providing improved transmission and reduced reflection.
The geometry of the lens includes an edge thickness of 1.41mm and a center thickness of 3mm. The effective focal length (EFL) is 18mm, and the radius of curvature (R1) is 12.11mm. The lens has no inner or outer radius, indicating a uniform thickness across the lens.
The lens is currently in stock and available for immediate purchase. For more information, you can refer to the vendor's website through the provided weblink.
