This is a high-quality Plano-Convex lens, type G052115322, manufactured by Qioptiq Photonics. The lens has a diameter of 12.7 mm and a thickness of 2.7 mm at the edge, with a center thickness of 3 mm. The effective focal length (EFL) of this lens is 150 mm, making it suitable for a wide range of optical applications.
The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The N-BK7 Schott material ID indicates that this specific lens is made of high-quality N-BK7 glass, sourced from Schott, a renowned glass manufacturer.
The lens is designed for use in the visible light spectrum, specifically between 450 and 700 nm, with a peak wavelength of 588 nm. It features a broadband anti-reflection coating on both the front and back surfaces, denoted as 'qio bbar arb2visnbk7'. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The lens is spherical in shape, with a radius of curvature (R1) of 77.179 mm on the convex surface. The inner and outer radii are both zero, indicating that this lens does not have any concave surfaces or threads.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more information, please refer to the provided weblink.
