G311377329 12.5 mm Dia. N-BK7 Double-Convex Lens; EFL=12.5mm 1064nm
This is a high-quality lens from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens, identified as G311377329, is a double-convex spherical lens with a diameter of 12.5 mm and a center thickness of 4.5 mm. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, particularly its high refractive index and low dispersion.
The lens has an effective focal length (EFL) of 12.5 mm, which is also its diameter, making it a symmetrical convex-convex lens. The front and back radii of the lens are 11.971 mm and -11.971 mm, respectively, indicating a strongly converging lens. The lens is unmounted, providing flexibility for users to integrate it into their optical systems as needed.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating is designed to reduce reflection and enhance transmission at a wavelength of 1064 nm, making the lens suitable for use in Nd:YAG laser systems. The coating also provides excellent environmental stability, ensuring the lens maintains its performance over time.
