The Optical Multi-Parameter Analyser (OMPA) is used to characterise liquid crystals.
The SRSG enhanced the existing OMPA MATLAB application by implementing a database and user interface for managing liquid crystal parameters. The database stores parameters including Liquid Crystal identification and the temperature at which the parameters were characterised. The parameters include the dielectric permittivity tensor, the bend, splay and twist elastic constants, the Lesley viscosity coefficients, and the refractive indices at different wavelengths along with sources for any cited data.
The software also makes the data more accessible via a database user interface in MATLAB.
