G312312322 40 mm Dia. N-BK7 Plano-Convex Lens; EFL=50mm 450-700nm
The G312312322 is a 40 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics. This 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 has a focal length (EFL) of 50mm, making it suitable for a wide range of applications that require moderate magnification.
The lens's geometry is characterized by a convex surface with a radius of curvature of 26.42mm. The edge thickness is 2.6mm, while the center thickness is 11.8mm. The lens is unmounted, providing flexibility for users to integrate it into their optical systems according to their specific requirements.
The G312312322 lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's performance in the visible spectrum (450-700nm), reducing reflection and increasing transmission.
