This is a G063355329 Plano-Concave Lens, a spherical lens with a base shape of a circle, sourced from Qioptiq Photonics. The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -150mm, making it a negative or diverging lens, which spreads out light rays. The lens is made of UVFS material with the Mal-1965 ID.
The lens is designed to operate at a wavelength of 355 nm and 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 also Qio HP Nbar Arhs-Yag. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it suitable for high-power laser applications.
The lens is mounted and fused silica, ensuring durability and stability. It is currently in stock and available for purchase on the Qioptiq Photonics website. For more detailed information and specifications, please refer to the provided weblink.
