Surface roughness measurement is complex, and is defined in different ways by different International Standards. To accommodate this, the Talysurf can be configured to output results to any one of a range of different International Standards. This leads to a wide range of “standard” parameters that the Talysurf can measure, e.g. amplitude (Rp, Rv, Rz, Rzi, Rmax etc.), surface average (Sa, Sq, etc.), unfiltered (Pa, Pq; etc.); the parameter definition being in accordance with whichever International Standard option is selected.
The Talysurf can generate on-screen both 2d and 3d colour-coded contour maps of the texture of the sampled surface of the optic. Any anomalies can be easily seen among the microscopic peaks and valleys of the surface. Scales and orientation can be adjusted to aid visualisation of surface defects.
2D profiles can also be extracted and presented graphically to examine the amplitude of the surface along specific user-defined paths.
The Talysurf can compile its measurements into accurate surface analysis reports. At Crystran we use these reports typically in internal quality control, although they may also be provided to customers, on request, as an additional service.
