Learn how optical modelling can help to improve your production Take a look at our latest hardware product Research Thin film analysis by spectrum simulation techniques Advanced models for optical constants Spectral ray-tracing investigations Direct determination of optical constants Realistic modeling of diffuse reflectance spectra Design
- WTheiss Hardware and Software | Hardware and software for optical . . .
Surface roughness, porous materials or mixtures of 2 phases require the computation of effective optical constants Unfortunately, there is not a unique way of mixing optical constants Our software packages have the following implementations for effective material properties: Bruggeman model (also known as EMA = Effective Medium Approximation)
- The OJL model - mtheiss. com
The so-called OJL model for interband transitions is due to [S K O'Leary, S R Johnson, P K Lim, J Appl Phys , Vol 82, No 7, 1 October 1997] where expressions for the density of states (DOS) are given for the optical transition from the valence band to the conduction band

This PDF-document explains how the SPRAY ray-tracing software can be used to predict the optical appearance of printed patterns DLL package Most of our products require some dynamic link libraries (DLLs) which must be copied to the Windows system directory (the folder c: windows system32 in most cases) or the program folder of the application
- Main Software Products
Graphically varying thicknesses or optical constant parameters you can easily inspect and optimize coating properties Investigate systematically the consequences of parameter variations and fluctuations (due to production tolerances) and create corresponding charts
- SCOUT technical manual - mtheiss. com
The interpretation of optical spectra is the central task of SCOUT - this manual gives technical information about the program features Discussions of successful SCOUT applications are found on our homepage www mtheiss com and in the tutorials accompanying this document
- SCOUT2 - mtheiss. com
Unlimited number of user-defined views of selected spectra, optical constants or parameter values in the main window, arbitrary bitmaps and metafiles as background pictures, illustrations and explanation
- Overview gt; Introduction
In more advanced solutions an optical model is fitted for the currently produced coating, and information about film thicknesses and film composition is extracted
