G314331331 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-30mm
This is a Plano-Concave lens with a diameter of 12.7 mm, sourced from Qioptiq Photonics. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens has a center thickness of 1.5 mm and an effective focal length (EFL) of -30 mm, making it suitable for applications that require a concave lens.
The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a plano surface on one side and a concave surface on the other. The concave surface has a radius of curvature (R1) of -15.51 mm.
The lens is designed to operate at a wavelength of 588 nm. It comes with a coating on both the front and back surfaces, specifically Qio AR AL RALVIS AOI 45. This coating is designed to reduce reflection and improve transmission, making the lens more efficient in its intended application.
