67-491 10.0mm Dia. x 75.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

This is a 10.0mm diameter, 75.0mm focal length Plano-Convex lens, specifically designed for use in the Near-Infrared (NIR) spectrum, covering the wavelength range of 750-1550nm. The lens is sourced from the reputable optical vendor, Edmund Optics.

The lens is made from the high-quality material, N-BK7 Schott, which is known for its excellent optical properties and durability. The lens has a front surface curvature radius of 20.67mm and a back focal length of 38.02mm. The edge thickness of the lens is 2.39mm, while the center thickness is 3mm, providing a robust structure for various applications.

The lens features a standard NIR-II coating on both the front and back surfaces, which is specifically designed to enhance performance in the NIR spectrum. This coating helps to reduce surface reflections and increase transmission, thereby improving the overall efficiency and quality of the optical system.

The lens is spherical in shape, which is a common and versatile geometry in optical systems. The lens is in stock and ready for immediate shipping, as indicated by the "weblink status" field in the item data.
