Optimized optics

The FVS-6000 employs a 28° interferometer to reduce polarization effects and reflective optics to eliminate artifacts caused by birefringence for high-quality VCD data. The isolated mount of the IR light source and the thermal control of the PEM crystal offers long-term baseline stability.

VCD auto alignment

The auto alignment function optimizes the VCD optics to reduce linear anisotropy artifacts. No manual alignment is required when the detector and/or optical filters are exchanged.

Lock-in detection by DSP

Phase-sensitive lock-in detection by DSP (Digital Signal Processing) with a sophisticated algorithm optimized for VCD offers drastic improvement of the S/N ratio.

Purge capability

The optics, sample chamber and detector housing are all purgeable to obtain high-precision data free of environmental interference.
