G314333331 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-100mm
This is a Plano-Concave lens with a 12.7 mm diameter, sourced from Qioptiq Photonics. The lens is made of N-BK7 glass, a popular material in the optical industry due to its excellent optical properties and versatility. The lens's design includes a center thickness of 1.5 mm and an effective focal length (EFL) of -100 mm, making it suitable for applications that require a concave lens.
The lens's geometry is spherical, with a radius of curvature (R1) of -51.212 mm for the concave surface. The lens's inner and outer radii are both zero, indicating a plano surface on one side.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating enhances the lens's performance in specific wavelength ranges, in this case, 588 nm, by reducing reflection and improving transmission.
Please note that the lens is unmounted, meaning it does not come with any housing or mounting hardware. This allows users to integrate it into their systems according to their specific requirements. The lens is currently in stock and available for purchase through the provided weblink.
