G312356322 12.7 mm Dia. N-BK7 Plano-Convex Lens; EFL=200mm 450-700nm

This is a G312356322 12.7 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, and has a planar (flat) surface on one side and a convex surface on the other. The lens's effective focal length (EFL) is 200mm, making it suitable for applications that require moderate magnification.

The lens is designed to work within the wavelength range of 450-700nm, which covers the visible light spectrum. It comes with anti-reflection coatings on both the front and back surfaces, specifically Qio Bbar Arb2visnbk7 coatings, which are optimized for use in the visible spectrum. This coating helps to reduce surface reflections, improving the overall transmission of light through the lens.

The lens has a diameter of 12.7mm and a thickness of 2.8mm at the edge, increasing slightly to 3mm at the center due to the curvature of the convex surface. The inner radius is 0mm, and the outer radius is also 0mm, indicating that the lens is a simple plano-convex design without any additional features such as threads or mounts.

This lens is a versatile optical component, suitable for a wide range of applications, including but not limited to, imaging systems, beam shaping, and laser applications. It is currently in stock and available for purchase through the Qioptiq Photonics website.
