Application: thickness measurement of wafer, PET-bottles and plastic foils
The new optical sensor for thickness measurement from Precitec Optronik is the CHRocodile IT 18 – 3000.
The CHRocodile IT 18 – 3000 covers the largest measuring range in the IT series of proven and highly precise CHRocodile sensors. The measuring range in air extends between 18 – 3000 µm. This corresponds to a measuring range of 5 – 800 µm in silicon (refractive index n ≈ 3.6). For film or plastic (n ≈ 1.5) the measuring range is between 12 and 2000 µm.
With the new CHRocodile IT 18 – 3000 the user can measure inline the thickness of the following materials:
- Rough-cut or textured wafers
- Opaque and scattering materials, for example PP- and PET-bottles
- Multilayer systems, for example foils and bonded wafers
