1. Various surfaces can be measured: mirror, curved or tilted mirror, rough surface, transparent, droplet surface, etc., are easy to measure.

2. No shadow effect: light shines from all sides to the sample, the laser principle is blocked in one direction can not be measured, confocal easy to solve

3. High resolution: Theoretically the wavelength can be subdivided all the way down, and the ideal lens has a fairly high resolution.

4. Good temperature stability: the lens itself does not heat, and the temperature drift is small. For micron and submicron measurements, temperature drift is key.

5. Automatic focusing: Within the range, the position of the measured object changes up and down, and the corresponding wavelength of light is focused to the surface of the object.

6. High horizontal resolution: from top to bottom, it is always in the focus, and the measured light spots are small, and the small contour changes on the measured object can be distinguished.

7. Modular miniaturization: the lens and controller can be connected through optical fiber, the transmission distance is far, the lens can be made small, easy to install side by side.

8. FM interference: the wavelength is an FM signal, which is not sensitive to AM interference such as light intensity change. Optical fiber is not sensitive to electromagnetic interference and lightning surge.

9. Transparent material thickness measurement: When the measured object is transparent and has two surfaces, there will be two wavelengths of light returned to obtain the thickness value.

10. Holography: In theory, the wavelength of any beam of light returning to the spectral analyzer carries distance information, and some light is shielded.

11. High safety: long life LED light source, small power white light, safer than laser for the human eye, not limited to the laser hazard level.

12. High protection: The controller has high protection level, and the optical fiber can be provided with stainless steel jacket version to prevent pests and rats from biting.
