Test Procedures

Place the sample on the precision stage and secure it properly.

Select the appropriate measurement mode, such as white light interferometry or phase-shifting interferometry.

Adjust the zoom optics and focus position according to sample characteristics.

Initiate automatic scanning to acquire surface data without physical contact.

Enable automatic stitching if large-area surface measurement is required.

Analyze roughness, step height, film thickness, and three-dimensional topography using the analysis software.

Maintenance Information

Keep optical components clean to ensure stable measurement accuracy.

Periodically check the calibration status of the precision stage.

Ensure the LED illumination system operates correctly across all wavelength bands.

Store the instrument in a clean, vibration-free environment when not in use.

Perform routine system inspections to maintain long-term measurement reliability.
