49-982 20mm Dia. x 80mm FL VIS 0deg Coated; UV Plano-Convex Lens VIS 0° 425-675nm
This product is a 20mm diameter, 80mm focal length plano-convex lens, offered by Edmund Optics. The lens is designed for use within the visible light spectrum, specifically between 425 and 675 nanometers. The lens features a standard anti-reflection coating on both the front and back surfaces, which is optimized for visible light at 0 degrees. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The lens is made from fused silica, a material known for its excellent optical properties, including a low coefficient of thermal expansion and high resistance to thermal shock. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens surface. The edge thickness of the lens is 1.61mm, while the center thickness is 3mm.
The lens is designed for use in a variety of applications, including imaging systems, beam shaping, and light collimation. Its high-quality construction and precise specifications make it suitable for use in demanding optical systems. The lens is currently in stock, according to the vendor's website.
