This is a 31.5 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics, a leading provider of precision optics. The lens is made of N-BK7, a popular type of borosilicate glass known for its excellent optical properties, including a high refractive index and low dispersion.
The lens features a focal length (EFL) of 500mm, making it suitable for applications that require moderate to high magnification. The plano-convex design, where one side is flat and the other is curved, allows for efficient light gathering and focusing.
The lens has a thickness of 2mm at the edge and 2.5mm at the center. The curvature of the lens is defined by a radius (R1) of 259.476mm. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
This lens is currently in stock and available for purchase on the Qioptiq Photonics website. It can be used in a variety of applications, including imaging systems, beam shaping, and optical testing.
