This is a G063317322 model lens, a product of Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens is spherical in shape, specifically a symmetric convex-convex lens, and is mounted on fused silica, also known as UVFS.
The lens has a base shape of a circle with a diameter of 22.4 mm. The edge thickness is 1.5 mm, while the center thickness is 6 mm. The effective focal length (EFL) of the lens is 30 mm, making it suitable for a wide range of optical applications.
The lens's front and back surfaces are coated with Qio Bbar Arb2visnbk7, a coating that enhances its performance in the 450-700nm wavelength range. This coating is designed to provide broadband anti-reflection, making the lens ideal for use in various optical systems.
The item data also provides the radii of the lens surfaces, R1 and R2, which are 29.007 mm and -29.007 mm respectively. The inner and outer radii are both zero, indicating that the lens has a uniform curvature.
