A modified thermomechanical analyzer is described as an useful tool to study the
photoinduced changes in the viscous flow and thermal properties of glassy materials.
The device proposed was tested on model chalcogenide glass As2S3 using the
penetration method. Further, the article discusses and summarizes the effect of the light
illumination (at wavelength of 650 nm) on the viscous flow at different temperatures
below the glass transition temperature (Tg), and on the thermal behaviour interpreted
from dilatometric curves via glass transition temperature and softening temperature.
