This is the G052314322 model from Qioptiq Photonics, a 10 mm diameter Plano-Concave lens made of UVFS material. The lens features a negative focal length (EFL) of -16mm, making it suitable for applications that require light convergence. The lens is designed to work within the wavelength range of 450-700nm, which covers the visible light spectrum.
The lens is mounted and fused with silica, ensuring durability and stability. It has a center thickness of 1mm, providing a reasonable balance between weight and optical performance. The lens's geometry is spherical, with a radius of curvature of -8.175mm for the concave surface. The lens's inner and outer radii are both zero, indicating a uniform curvature across the lens surface.
The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible light spectrum, reducing reflection and increasing transmission. The lens's base shape is circular, making it compatible with a wide range of optical systems.
