G312407331 31.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=500mm

The G312407331 is a 31.5 mm diameter Plano-Convex lens, sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics. This lens is designed for use in a wide range of optical systems, offering a focal length of 500mm, indicated as EFL (Effective Focal Length) in the specifications.

The lens is fabricated from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. The Plano-Convex geometry, where one side is flat and the other is curved, is a common choice for applications that require a simple, yet effective lens design. The lens has a center thickness of 2.5mm and an edge thickness of 2mm, providing a robust structure while maintaining a low profile.

The lens features a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as 'qio al ralvis aoi 45', is designed to minimize surface reflections and increase transmission across the visible spectrum, specifically at the wavelength of 588nm.

The G312407331 is currently in stock and available for immediate purchase through the Qioptiq Photonics website. With its high-quality materials, precise geometry, and advanced coating, this lens is an excellent choice for various optical applications.
