This is a Plano-Concave Lens from Qioptiq Photonics, a leading provider of precision optics. The lens has a diameter of 10 mm and a center thickness of 1 mm. It is designed for use with a wavelength of 355 nm and features a focal length (EFL) of -16 mm, making it suitable for applications that require a negative focal length.
The lens is made from UVFS material with the Mal-1965 index. The front and back surfaces of the lens are coated with Qio HP Nbar Arhs-Yag, providing enhanced durability and performance. This coating is specifically designed for use with YAG lasers, making it an ideal choice for applications in this field.
The lens is spherical in shape, with a radius of curvature (R1) of -8.175 mm on the concave surface. The inner and outer radii are both 0, indicating a uniform curvature across the lens.
The lens is currently in stock and available for purchase. More information, including pricing and delivery times, can be found on the Qioptiq Photonics website.
