NS Touch Bending Surface facial mask Thickness Meter (handheld) is an excellent handheld film measurement system with significant price advantage, can be used for testing the thickness of the hardened film on eyeglass lensesIt can quickly analyze the reflection spectrum data of thin films within a few seconds and analyze the thickness of single-layer and multi-layer thin films. The dedicated handheld probe facilitates the measurement of curved surfaces such as glasses and car lights.

1ACUITIK NS Touch surface thickness measurementMain functions of the instrument
1. Anti reflective coating thickness measurement (AR Coating)
-Easy to operate: Measure the anti reflection film on curved glasses and other optical lenses.
2. Measurement of Hard Coating Thickness
-It is possible to measure the thickness of both the hard coating and the primer layer simultaneously.
3. Measurement of thickness of hydrophobic layer
-The hydrophobic layer is very thin, only about a hundred atoms thick, so short wavelength ultraviolet light is needed for measurement.
2、 Features of NS Touch curved surface facial mask thickness meter (handheld)
1. Easy Calibration: The AutoCal algorithm frees users from the tedious process of daily calibration.
2. Improve accuracy: Minimize back reflection interference to ensure more accurate and reliable measurement results.
3. Easy operation: Thanks to the automatic sample detection algorithm, the measurement process is intuitive and easy to use.
