This is a G052404329 12.7 mm diameter N-BK7 mounted double-concave lens, specifically designed for use with a wavelength of 1064nm and an effective focal length (EFL) of -100mm. 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 circular. The first radius of curvature (R1) is -104.41mm, while the second radius of curvature (R2) is 104.41mm, indicating a symmetric concave-concave design. The lens has a center thickness of 1.5mm. The inner and outer radii are both 0mm, suggesting a simple, double-concave design.
The lens is made from N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and wide transparency range. The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces, providing anti-reflection properties and ensuring high transmission efficiency.
The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website at https://www.qioptiq-shop.com/en/Precision-Optics/Singlets/Symmetric-Concave-Lenses/Symmetric-concave-lenses-mounted-N-BK7.html.
