Optical Thickness Meter OPTM series

This instrument enables extremely precise analysis of film thickness and optical constants by measuring absolute spectral reflectance of microscopic regions.
Non-destructive and non-contact thickness measurement can be carried out on multilayered films and various coating layers including films, wafers, and optical materials.
Measurement speed is as fast as 1 second / point. Software is easy to use even for beginner users analyzing optical constants.

Product

Features
  • All functions necessary for film thickness measurements are integrated in the head
  • Highly accurate absolute reflectance measurement using microspectroscopy (thickness of multilayered film and optical constants)
  • High speed measurement of less than 1 second per point
  • An optical system which makes possible measurement with a wide wavelength range (UV to NIR) using microscopy
  • Safety mechanism with area sensors
  • Easy Analysis Wizard which allows anyone- even untrained operators, to carry out the analysis of optical constants without difficulty
  • Software program includes macro functions for customization of the measurement sequence
  • Various customizations are possible

The measurement sequence can easily be customized depending on the shape and/or the position of the sample.

The measurement sequence can easily be customized depending on the shape and/or the position of the sample.
