G052310000 12.7 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-200mm Uncoated
This is a 12.7 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, featuring a center thickness of 1.5 mm and an effective focal length (EFL) of -200 mm. The lens is made of N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion properties.
The lens's geometry is spherical, with a radius of curvature (R1) of -102.92 mm. The inner and outer radii are both zero, indicating a plano surface on one side and a concave surface on the other. The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces.
This lens is designed for use at a wavelength of 588 nm. It is mounted, making it ready for immediate use in optical systems. The lens's information, including a link to its product page, is available on the Qioptiq Photonics website, where it is listed as in stock.
