G063063329 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-150mm 1064nm
This is a G063063329 model lens from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens is a symmetric concave type, featuring a base shape of a circle, and is mounted for convenience.
The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm. It has an effective focal length (EFL) of -150mm, indicating its double-concave nature. The first radius of curvature (R1) is -156.22 mm, and the second radius (R2) is 156.22 mm, further emphasizing its concave design.
The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is designed to operate at a wavelength of 588 nm.
The lens comes with a coating on both the front and back surfaces. The front coating is Qio HP Nbar Arhs-Yag, and the back coating is the same. This coating enhances the lens's performance by reducing reflection and increasing transmission.
The lens's shape is spherical, a common choice for its ease of manufacturing and versatility. The lens is currently in stock and can be purchased from the Qioptiq Photonics website.
