47-391 40.0mm Dia. x 300.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-391 is a Plano-Convex lens with a diameter of 40.0mm and a focal length of 300.0mm. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical elements. The lens is designed for use in the visible to near-infrared spectrum, covering the wavelength range of 400-1000nm, making it suitable for a wide range of applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The Plano-Convex geometry, where one side is flat and the other is curved, is a common design for optical lenses. This particular lens has an inner radius of 0mm and an outer radius of 0mm, with a center thickness of 5mm and an edge thickness of 3.7mm.
The lens features a VIS-NIR coating, denoted as edm visnir0sp2002000, on both the front and back surfaces. This coating is designed to enhance the lens' performance in the visible to near-infrared spectrum, reducing reflection and increasing transmission. The coating status is currently in stock, ensuring quick and reliable delivery.
