G311377400 12.5 mm Dia. N-BK7 Double-Convex Lens; EFL=12.5mm
This is a G311377400 12.5 mm Dia. N-BK7 Double-Convex Lens, with a focal length (EFL) of 12.5mm, sourced from Qioptiq Photonics. The lens is a spherical design, featuring a symmetric convex-convex shape, and has a base shape of a circle.
The lens has a diameter of 12.5mm, with a center thickness of 4.5mm and an edge thickness of 1mm. The inner and outer radii are both zero, and the radii of curvature are 11.971mm for both the front and back surfaces.
The lens is made of N-BK7, a type of borosilicate glass, which is known for its excellent optical properties and durability. The glass has a refractive index of 1.5168 at the specified wavelength of 587.6nm.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website at https://www.qioptiq-shop.com/en/Precision-Optics/Singlets/Symmetric-Convex-Lenses/Symmetric-convex-lenses-unmounted.html.
