Overview

Non contact optical thickness gauge is a measurement device based on spectral confocal imaging technology, designed specifically for micrometer level precision detection requirements. This device emits polychromatic light through a broad-spectrum LED light source, which is focused by a dispersive lens to form a continuous wavelength focal point, accurately capturing the confocal wavelength signal reflected from the surface of the object. Combined with high-speed spectral analysis algorithms, it achieves a sampling frequency of up to 10kHz at a single point and ultra-high resolution of 0.1 μ m. The equipment adopts a natural granite platform and a hidden inverted probe, providing stable measurement benchmarks and reducing layout obstacles. It supports single-layer or multi-layer thicknesses of transparent/non transparent materials (such as coatings and substrates)

productIntroduction

Non contact optical thickness gaugeIt is a measurement device based on spectral confocal imaging technology, designed specifically for micrometer level precision detection needs. This device uses a wide spectrumThe LED light source emits polychromatic light, which is focused by a dispersive lens to form a continuous wavelength focal point, accurately capturing the confocal wavelength signal reflected from the surface of the object. Combined with high-speed spectral analysis algorithms, it achieves a sampling frequency of up to 10kHz and ultra-high resolution of 0.1 μ m at a single point. The equipment adopts a natural granite platform and a hidden inverted probe, providing stable measurement benchmarks and reducing layout obstacles. It supports synchronous non-destructive testing of transparent/non transparent materials with single-layer or multi-layer thickness (such as coating+substrate), and is applied in the field of optical glass manufacturing

Product Features

1. Wide range (± 2000 μ m), high resolution (100 nanometers), linear error<± 0.8 μ m

2. No contact with the surface of the tested object, avoiding scratches, indentations, or stress effects

3. Embedded inverted probe to prevent probe from affecting the layout path

4. Fast measurement speed (10000 points per second), suitable for dynamic process monitoring

5. Support multi-layer thickness measurement

6. Flexible triggering modes (manual, real-time)

7. Data with serial number (can be matched with a barcode scanner)

8. Support data upper and lower limit management (qualification judgment)

9. Real time visualization (thickness values, tables, spectra)

10. Convenient data export (TXT, EXCEL, HTML)
