This is a mounted double-convex lens, type G063853525, from Qioptiq Photonics. The lens has a diameter of 25.4 mm and a mount thickness of 5 mm. The center thickness of the lens is 7 mm, and it has an effective focal length (EFL) of 80 mm. The lens is made of N-BK7 Schott glass, a popular choice for its excellent optical properties and high damage threshold.
The lens's front and back surfaces are coated with qio bbar arb2nirnbk7, a coating that enhances the lens's performance in the 725-1050nm wavelength range. This coating reduces reflection and increases transmission, making the lens suitable for use in high-power laser applications.
The lens's geometry is spherical, with a first radius (r1) of 81.166 mm and a second radius (r2) of -81.166 mm. The lens's inner and outer radii are zero, indicating a symmetrical design.
The lens is in stock and available for purchase on the Qioptiq Photonics website. For more information, please refer to the provided weblink.
