G312404329 31.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=150mm 1064nm
This is a Plano-Convex Lens, type N-BK7, from Qioptiq Photonics, designed for use in precision optics applications. The lens has a diameter of 31.5 mm and an effective focal length (EFL) of 150 mm at a wavelength of 1064 nm. The lens is made of N-BK7 glass, a popular choice for its high homogeneity and low auto-fluorescence.
The lens has a front coating of Qio HP Nbar ARHS-YAG and a back coating of the same, providing excellent anti-reflection properties. The edge thickness of the lens is 2.4 mm, while the center thickness is 4 mm. The lens's geometry is spherical, with a radius of curvature (R1) of 78.02 mm on the convex side. The inner and outer radii are both zero, indicating a plano surface on the other side.
This lens is available for purchase from the Qioptiq Photonics website, where it is listed as in stock. The item data also provides a weblink to the product page for easy access.
