This is a G063347329 model lens, a product of Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens is spherical in shape, with a base shape of a circle, and is designed for use in ultraviolet, visible, and shortwave infrared regions of the spectrum, as indicated by its UVFS material ID.
The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm. It features a double-concave geometry, with both radii of curvature being equal at 50.481 mm. This design results in an effective focal length (EFL) of -50 mm, making it suitable for applications that require a negative focal length.
The lens is mounted and has an inner radius of 0 mm and an outer radius of 0 mm. It is designed to operate at a wavelength of 355 nm. The lens comes with a front and back coating of Qio HP Nbar ARHS-YAG, which is a high-performance anti-reflection coating designed for use in YAG laser systems.
The lens is currently in stock and can be purchased directly from the Qioptiq Photonics website. For more information, please refer to the provided weblink.
