G312010329 8 mm Dia. N-BK7 Plano-Convex Lens; EFL=8mm 1064nm
This is a Plano-Convex Lens, type N-BK7, from the renowned optical components manufacturer, Qioptiq Photonics. The lens has a circular base shape with a diameter of 8 mm and a thickness of 0.91 mm at the edge, increasing to 4 mm at the center. The effective focal length (EFL) of this lens is 8 mm, making it suitable for applications that require a compact, high-performance lens.
The lens is made from N-BK7, a popular glass type known for its excellent optical properties, including a high Abbe number and low dispersion. This makes it an ideal choice for applications that require high precision and accuracy, such as laser systems, metrology, and imaging.
The lens features a Qio HP Nbar ARHS-YAG coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, particularly at the 1064 nm wavelength. This makes the lens suitable for use in Nd:YAG laser systems, which often operate at this wavelength.
The lens's geometry is spherical, with a radius of curvature of 4.13 mm on the convex side. The inner and outer radii are both 0, indicating a flat surface on the other side. This geometry is common in optical systems that require a simple, single-element lens.
