G312407322 31.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=500mm 450-700nm
The G312407322 is a Plano-Convex lens with a diameter of 31.5 mm, sourced from Qioptiq Photonics. This lens is designed for use in the visible spectrum, with a wavelength of 588 nm. The lens is made from N-BK7, a popular optical glass known for its excellent transparency and low auto-fluorescence.
The lens features a focal length (EFL) of 500 mm, making it suitable for applications that require moderate magnification. The front and back surfaces of the lens are coated with qio bbar arb2visnbk7, a broadband anti-reflection coating that enhances transmission in the 450-700 nm range.
The lens has a center thickness of 2.5 mm and an edge thickness of 2 mm, providing a good balance between weight and optical performance. The curvature of the lens is defined by a radius of 259.48 mm on the convex side. The lens is unmounted, allowing for flexibility in integration into optical systems.
