G312357331 12.7 mm Dia. N-BK7 Plano-Convex Lens; EFL=300mm
This is a Plano-Convex Lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a circular base shape and a diameter of 12.7 mm. The thickness at the edge of the lens is 2.9 mm, while the thickness at the center is 3 mm. The effective focal length (EFL) of this lens is 300 mm, making it suitable for applications that require long focal lengths.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The front and back surfaces of the lens are coated with "qio al ralvis aoi 45", a coating that likely enhances the lens's performance in specific wavelength ranges.
The lens's geometry is such that it has a curved convex surface and a flat plano surface. The radius of curvature of the convex surface is 153.99 mm. The lens does not have an inner or outer radius, indicating that it is a simple, unmounted lens.
This lens is available for purchase from the Qioptiq Photonics website, where it is listed as being in stock. The provided weblink leads directly to the product page for easy access.
