Abstract: Recently, ellipsometry and polarization imaging using photoelastic modulators (PEMs) have been applied to a wide spectral range, from vacuum ultraviolet to the mid-infrared wavelengths.
The new PEM has the same high sensitivity (10-6), wide acceptance angle (±40°), and modulation purity as previous generations. Available wavelength ranges are
CASTECH''s photoelastic modulator has the advantages of wide receiving angle, large clear aperture, wide wavelength range, high modulation frequency and high precision.
Measurements of circular dichroism (CD) in the UV and vacuum UV have used photoelastic modulators (PEMs) for high sensitivity (to about 10-6). While a simple technique for wavelength calibration of the
