G313216329 22.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm 1064nm
This is a G313216329 double-concave lens, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and versatility. The lens has a double-concave geometry, meaning it is curved inward on both sides, with radii of curvature R1=-104.41mm and R2=104.41mm. This particular lens has an effective focal length (EFL) of -100mm at a wavelength of 588nm.
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, making it suitable for use in high-power laser applications, particularly at the 1064nm wavelength. The lens's shape is spherical, a common choice for its simplicity and wide range of applications.
This lens is available from Qioptiq Photonics, a leading vendor in the field of precision optics. According to the vendor, the lens is in stock and ready for immediate shipping. For more information, including technical specifications and pricing, please refer to the vendor's website.
