3D schematics of the far-IR Ellipsometer at U4-IR beamline, NSLS. Standard configuration consists of PSG  and PSA sections, ARS optical cryostat, double-circle  Huber goniometer, and the X-Y-Z-c sample positioning system (Huber components). The optical cryostat is mounted on the q- table of the goniometer. The PSA section and bolometer are mounted on the 2q-arm of the goniometer.

Welcome to the far-IR Ellipsometer Project

The instrument is installed  at  the U4-IR beamline, NSLS, and is open for beamtime application through GUP system at NSLS-BNL
