G314001525 6 mm Dia. N-BK7 Plano-Concave Lens; EFL=-6mm 725-1050nm
This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a base shape of a circle and a diameter of 6 mm. The center thickness of the lens is 0.5 mm. The effective focal length (EFL) of this lens is -6 mm, making it a negative lens. The radius of curvature (R1) is -3.101 mm. The inner and outer radii are both 0 mm, indicating that the lens is uniformly curved from the center to the edge.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The wavelength for this lens is 588 nm.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance by reducing reflection and increasing transmission.
The lens is available in the visible and near-infrared spectrum, specifically designed for use in the 725-1050 nm range. According to the vendor's website, the lens is currently in stock.
