1 Maximum field of view with 2/3” camera and 0.375X optics. 2 Pixel size on the surface. 3 L&S: Line and Space, half of the diffraction limit according to the Rayleigh criterion. Spatial sampling could limit the optical resolution. Values for white LED. 4 Measurement speed 1X. 5 System noise measured as the difference between two consecutive measures on a calibration mirror placed perpendicular to the optical axis. 6 On smooth surfaces, up to 86º on rough surfaces.
