| A stable instrument guaranteeing accurate and repeatable measurements
The analysis of the fringes is performed using the technique of Spatial Carrier Phase Shifting (SCPS) for an acquisition time very short (about 1ms) and operated only one interferogram. The reconstruction of the wavefront is therefore more dependent on measurement conditions. The phase is calculated quickly and accurately.
Optionally, we can offer a wide range of spheres of reference (compatible Zygo).
