G312329000 12.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=20mm Uncoated

The G312329000 is a Plano-Convex lens with a diameter of 12.5 mm, sourced from Qioptiq Photonics. This lens is designed for use in the visible light spectrum, specifically at a wavelength of 588 nm. The lens is made from N-BK7, a popular optical glass known for its excellent optical properties and high transmittance in the visible spectrum.

The lens features an effective focal length (EFL) of 20 mm, making it suitable for a wide range of optical applications. The Plano-Convex design, where one side is flat and the other is curved, allows for efficient light gathering and focusing. The radius of curvature of the curved surface is 10.44 mm.

The lens has a thickness of 1.4 mm at the edge and 3.5 mm at the center. Notably, it does not have any coating, which means it is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmittance, or providing other benefits, an uncoated lens can be a cost-effective choice for applications where such enhancements are not necessary.

The lens's geometry and material make it suitable for use in various applications, including imaging systems, beam shaping, and laser applications. It is currently in stock and available for purchase through the provided weblink.
