The RC2® design builds on 25 years of experience. It combines the best features of previous models with innovative new technology: dual rotating compensators, achromatic compensator design, advanced light source and next-generation spectrometer design. The RC2 is a near-universal solution for the diverse applications of spectroscopic ellipsometry.

ANISOTROPY APPLICATIONS
Generalized Ellipsometry
Traditional ellipsometry measurements are ideal for standard thin film characterization. However, more advanced measurements are required for anisotropic materials.
Generalized Ellipsometry collects six values compared to the standard two (Ψ, ∆). This additional information completely characterizes the cross-polarization of anisotropic samples.
Complete Mueller-matrix
The RC2 can characterize the full Mueller-matrix of a sample. This advanced data type ensures appropriate characterization of complex samples that are both anisotropic and depolarizing.
Liquid Crystal
Twisted nematic liquid crystal films introduce the complexity of an anisotropic film with a smoothly varying optical axis. With the thick liquid crystal layer sandwiched between glass substrates, the Mueller-matrix measurements insure the best measurement.
The complete Mueller-matrix was measured for a twisted liquid crystal. This enabled characterization of the optical axis twist and pre-tilt, and liquid crystal anisotropic refractive index.
