G052307331 12.7 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-30mm
This is a mounted plano-concave lens, type G052307331, manufactured by Qioptiq Photonics. The lens has a diameter of 12.7 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -30mm, indicating that it is a diverging lens.
The lens is made of N-BK7, a popular optical glass type known for its excellent optical properties and versatility. The curvature of the lens is spherical, with a radius of curvature (R1) of -15.51mm for the concave surface. The lens does not have an inner or outer radius, indicating that it is a simple plano-concave lens.
The lens is designed for use at a wavelength of 588nm. It comes with a coating on both the front and back surfaces. The coating is Qio AR Al RALVIS AOI 45, which is a broadband anti-reflection coating designed to reduce surface reflections and improve transmission.
