OptiLayer:  Your Partner in Design and Post-Production Characterization of Optical Coatings

 

Import options of OptiLayer

OptiLayer Thin Film software provides various options which enable you to conveniently import experimental data from various measurement devices. The program also has a software utility that allows the extraction of numerical data from any ASCII file. This utility makes OptiLayer compatible with other commercial thin film packages or with your own software. OptiLayer allows import of any other data from external files, namely, optical constants, design structures, light sources, and detectors.

Also, you can easily import of data files from other commercial software packages.

OptiChar and OptiRE are able to import data from almost all well-known spectrophotometers and ellipsometers and widely used data formats.

  • TFCalc data files
  • Essential Macleod data file
  • FilmStar FILM file
  • LZH design
  • Sopra n,k data
  • ZEMAX Glass
  • Bühler Leybold Dispersion Data
  • Bühler Leybold Monitoring Report
  • Optical Design eXchange file (ODX)
  • ODS files (OptiLayer Design Specification)

Import of data from Perkin Elmer spectrophotometers. You need  three clicks to transfer measurements from Perkin Elmer spectrophotometers.

In the same way the *.dx (JCAMP-DX) data files can be converted to OptiChar/OptiRE measurement database. 

Example: Import measured transmittance from Perkin Elmer spectrophotometer (average polarization, normal incidence, spectral units are nanometers, transmittance is given in %).

Import from Agilent spectrophotometers. OptiLayer allows import of data from Agilent Cary spectrophotometers.  Usually Agilent Cary files include several so-called traces. The list of available traces is shown in the left part of the dialog window.

import agilent data

It is possible to switch between different traces and view description of measurements and Preview data. In the newest OptiLayer version 12.12, the incidence angle and polarization are identified automatically. It is very easily to collect the multi-angle measurements in one file.

Import from two-column data files. This option is useful when it is necessary to import simple ASCII two-column files. Usually the first column is the wavelength (or wavenumber), while the second column is some characteristic (Reflectance, Transmittance, etc.).

This option can be used also when you import data from FTIR spectrophotometers.

Import from Excel, Origin. OptiLayer allows you to import measurements data, optical constants, targets, design structures, light sources, integral weights from MS Excel and Origin using Copy/Paste.

Example (right panel): target transmittance is a Gaussian and it is that this target is not standard. Hence, it is not possible to specify such a target using the OptiLayer target generator. You can import complicated targets from Excel, Origin etc. using Copy/Paste (left and right panels below).

The same is valid for refractive indices/extinction coefficients/light sources/detectoors/design structures.

Import from Woollam ellipsometers. Woollam files are ASCII files organized in 6 columns: Wavelength, Angle of Incidence, Psi, Delta, Tolerance for Psi, Tolerance for Delta.

Woollam files don't contain the information concerning wavelength units. For this reason after opening a file in the Woollam's format it is necessary to make a proper selection in the Units in Woollam file box, specifying actual units for the wavelength in the Woollam file (right panel).

Modern Woollam ellipsometers measures depolarization and transmittance as well. Depolarization measurements are recorded for each incidence angle after Psi, Delta measurements in the Woollam files. Measurement transmittance files contain spectral units, angle of incidence, transmittance values and tolerances.

Example (panels below): import of Psi and Delta and depolarization measured at 45, 55, and 65 degrees.

Similar import procedures exist for Horiba and Sentech ellipsometers.

Import from arbitrary text files. You can import measurements data/optical constants/design structures from any ASCII file. The columns can be separated by any delimiters.

Example: import of reflectance/transmittance data from a home-made spectrophotometer.import photometric data
