G052310329 12.7 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-200mm 1064nm
This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a diameter of 12.7 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -200mm, which is typical for Plano-Concave lenses and indicates that light rays will diverge after passing through the lens.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The curvature of the lens is defined by a radius of -102.92 mm on the concave side. The lens does not have an outer radius, and the inner radius is 0, indicating that it is a simple, single-sided curvature lens.
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, particularly at the 1064 nm wavelength.
The lens is mounted, making it ready for immediate use in optical systems. The web link provided leads to the product page on Qioptiq's website, where users can find more information and check the current availability of the lens.
