This is the G311212525 model from Qioptiq Photonics, a 22.4 mm diameter UVFS Double-Convex Lens designed for use in the 725-1050nm wavelength range. The lens is part of Qioptiq's Precision Optics category, specifically the Symmetric Convex Lenses section.
The lens is spherical in shape, with a base shape of a circle. It features a double-convex design, meaning it has two convex surfaces. The first surface (R1) has a radius of curvature of 149.62, while the second surface (R2) has a radius of curvature of -149.62. This design gives the lens an effective focal length (EFL) of 150mm.
The lens has a center thickness of 2.4mm and an edge thickness of 1.6mm. The inner and outer radii are both 0, indicating that the lens has a uniform thickness. The lens is made from UVFS material, specifically identified as UVFS Mal-1965 in the item data.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in specific wavelength ranges, contributing to its suitability for use in the 725-1050nm range.
According to the item data, the lens is currently in stock and available for purchase. The vendor's website provides more detailed information and purchasing options.
