This is a G312304525 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, which is unmounted and made of fused silica, has a diameter of 22.4 mm and a thickness varying from 1.5 mm at the edge to 2.1 mm at the center.
The lens's effective focal length (EFL) is 200mm, making it suitable for applications that require a longer focal length. The lens is designed to work within the wavelength range of 725-1050nm, which includes near-infrared (NIR) and short-wave infrared (SWIR) regions.
The lens's front and back surfaces are coated with Qio Bbar Arb2nirnbk7, a broadband anti-reflection coating that reduces surface reflections and increases transmission. This coating is specifically designed for use in the NIR and SWIR regions, making it an ideal choice for applications in these spectral ranges.
The lens's geometry is spherical, with a radius of curvature (R1) of 100mm for the convex surface. The inner and outer radii are both zero, indicating a simple, single-curvature design. This lens is a precision optic, designed for use in applications that require high optical performance.
