This is a G063117329 Plano-Convex Lens, a spherical lens with a base shape of a circle, sourced from Qioptiq Photonics. The lens has a diameter of 31.5 mm and a thickness at the edge of 2.2 mm, while the center thickness is 3 mm. The effective focal length (EFL) of this lens is 300 mm, making it suitable for applications that require a longer focal length.
The lens is made of UVFS material with the ID MAL-1965. It is designed to work with a wavelength of 355 nm. The lens is coated on both the front and back sides with QIO HP NBAR ARHS-YAG, which is a type of anti-reflective coating that enhances the lens' performance in specific wavelength ranges.
The lens is mounted, indicating that it is ready to be integrated into an optical system. The specific mounting method or material is not detailed in the provided data. The lens' geometry is spherical, with a radius of curvature (R1) of 152.896 mm on the convex side. The inner and outer radii are both 0, suggesting that this lens does not have any additional features such as threads or flanges.
According to the vendor's website, this lens is in stock, making it readily available for purchase and use in your optical systems.
