AFL25-75-D-U-355

The asphericon AFL25-75-D-U-355 is a CNC grinded and polished asphere manufactured from quartz glass. Its diffraction-limited design ensures an outstanding surface form deviation (RMS < 0.02 µm) and lowest roughness (< 0.5 nm). This minimizes potential scattering and allows applications in high-power lasers and with ultra-short wavelengths.
