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, half of the diffraction limit according to the Rayleigh criterion. Spatial sampling could limit the optical resolution for interferometric objectives. Values for blue LED.
4 Measurement noise measured as the difference between two consecutive measures on a calibration mirror placed perpendicular to the optical axis. For interferometry objectives, PSI, 10 phase averages. The 0.01 nm are achieved with Piezo stage scanner and temperature-controlled room. Values for green LED (white LED for CSI). Values obtained in a VC-E vibration environment.
5 On smooth surfaces. Up to 86° on rough surfaces.
6 This is the weight of the sensor head with one objective in the turret.
