G311385322 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=80mm 450-700nm
This is a G311385322 12.7 mm diameter N-BK7 double-convex lens, specifically designed for use in the visible light spectrum, with an effective focal length (EFL) of 80mm. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens is spherical in shape, with a base shape of a circle. It features a double-convex design, characterized by two convex surfaces. The first surface has a radius of curvature (R1) of 81.166, while the second surface has an R2 of -81.166. This design allows for a high degree of light concentration and focusing.
The lens has a thickness of 2.5mm at the edge and 3mm at the center. The inner and outer radii are 0, indicating a symmetrical design. The N-BK7 material, a type of borosilicate glass, is known for its excellent optical properties, including a high refractive index and low dispersion.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, specifically between 450 and 700nm.
According to the vendor's website, this lens is currently in stock, making it readily available for immediate use. The website also provides further technical details and specifications for those interested in a more in-depth understanding of this product.
