G340177329 25.4 mm Dia. UVFS Plano-Concave Lens; EFL=-700mm 1064nm
This is a Plano-Concave lens, type of spherical lens, offered by Qioptiq Photonics. The lens has a base shape of a circle and a diameter of 25.4 mm. The center thickness of the lens is 5.8 mm. The effective focal length (EFL) of this lens is -700mm, which is unusual and indicates that this lens is designed to diverge light rather than converge it.
The lens is made of UVFS material with the Mal-1965 ID. It is designed to work with a wavelength of 355nm. The lens has a coating of Qio HP Nbar Arhs-Yag on both the front and back surfaces, which is presumably an anti-reflective coating designed for use with YAG lasers.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. The provided weblink leads directly to the product page for this lens.
