Optical Multi – Parameter Analyser (OMPA)
Compact, all-in-one device measuring elastic and viscosity parameters of liquid crystals (LCs), as well as providing wide area optical quality and uniformity analysis of LC devices.
Using single optical assembly and one LC sample, it determines the following LC parameters:
- Splay and bend elastic constants (K1 and K3)
- Rotation viscosity (γ1)
- Combination of Leslie viscosity coefficients (α4+ α5)
- Wide area mapping of LC layer thickness and alignment
Sample holder with thermal control enables measuring LC properties in a wide temperature range.
Easy-to-operate graphical user interface controls the measuring apparatus and performs the data analysis.
Standard LC cells or unique already encapsulated LC hybrid samples can be characterised.
Operates with a fiber coupled laser so that a variety of laser wavelengths can be used – chosen depending on sample requirements.
