Diverse observation: The episcopic illumination models of the ECLIPSE LV-N series allow for bright-field, dark-field, simple polarization, differential interference epi-fluorescence, and two-beam interference microscopy
Thus, a nondestructive, noninvasive tool such as interference microscopy or confocal microscopy is more suitable to monitor physical changes throughout the entire degradation process.
Three unexposed samples were used for the thickness measurements using SEM and interference microscopy techniques.
The techniques used to make measurements in an attempt to determine the TPO surface morphology have included X-ray microfocus fluoroscopy , visible-light differential interference microscopy
 and photoacoustic Fourier transform infrared spectroscopy .
Formation of two spherical nuage/ Balbiani bodies along the long axis of previtellogenic oocytes in Acheta domestica was demonstrated by differential interference microscopy
We used Nomarski interference filters on a Leica microscope to perform differential interference microscopy
at a magnification of 500X.
