1 Maximum field of view with 3/2” camera and 0.5X optics. 2 Pixel size on the surface. 3 L&S: Line and Space. Values for blue LED. 4 System noise measured as the difference between two consecutive measures on a calibration mirror placed perpendicular to the optical axis. For PSI, 10 phase averages with vibration isolation activated. The 0.01 nm are achieved with Piezo stage scanner and temperature controlled room. Values for green LED (white LED for CSI). Resolution HD.
5 On smooth surfaces, up to 71º. On scattering surfaces, up to 86º.
