This G314003329 optical lens, sourced from Qioptiq Photonics, is a 10 mm diameter Plano-Concave Spherical Lens with a center thickness of 1 mm. The lens is made of N-BK7, a popular optical glass, and features an effective focal length (EFL) of -10 mm at a wavelength of 588 nm.
The lens's geometry includes a concave surface with a radius of curvature of -5.168 mm, while the other surface is planar. The lens's design is circular, and it does not have any anti-reflective coating specified for the inner or outer surfaces.
The lens is available for purchase from the Qioptiq Photonics website, and as per the provided information, it is currently in stock. This lens could be suitable for applications that require a negative lens with a specific EFL and a particular radius of curvature.
