This is a G063323525 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 of the lens is 1.6 mm, while the center thickness is 2.2 mm. The effective focal length (EFL) of the lens is 200 mm, making it suitable for applications that require a longer focal length.
The lens's first radius of curvature (R1) is 199.53 mm, and the second radius of curvature (R2) is -199.53 mm, indicating that the lens is a double-convex lens. The inner and outer radii are both zero, suggesting that the lens does not have any additional shaping or contouring.
The lens is made of a material with the ID "uvfs mal- 1965". The wavelength of the lens is 355 nm. The lens is coated on both the front and back with "qio bbar arb2nirnbk7", a type of broadband anti-reflection coating that reduces reflection and increases transmission of light over a wide range of wavelengths.
