What is Differential interference contrast (DIC)?
Differential interference contrast (DIC) microscopy, also known as
Nomarski interference contrast (NIC) or Nomarski microscopy, is an
optical microscopy technique used to enhance the contrast in
unstained, transparent samples.
DIC works on the principle of interferometry to gain information
about the optical path length of the sample, to see otherwise
invisible features.
A relatively complex optical system produces an image with the
object appearing black to white on a grey background. This image is
similar to that obtained by phase contrast microscopy but without
the bright diffraction halo. The technique was developed by Polish
physicist Georges Nomarski in 1952.
Features:
iMet-230MDIC Reflected light differential interface contrast
microscope is a high capability price rate inspecting optical
instrument.
iMet-230MDIC adopts excellent infinity optics system, built-in high
brightness LED illumination, it is provided with differential
interface contrast observation function.
Trinocular/photography optical body, reflects the ture reduction of
visual observe, digital photography and microscopy technology
integration, the observed interface image has a stronger sense of
3D.
iMet-230MDIC is suitable for the microscopic morphology observation
of non-transparent material surface, such as microscopic morphology
of LCD conductive particles, it is the ideal instruments in quality
inspection, structural analysis of precision manufacturing.
Metallurgical microscopes provide polarization which makes it much
easier to view a variety of minerals, types of metals and even ink
samples. Material defect analysis is performed with a metallurgical
microscope in search of the causes of corrosion, fatigue, stress
fractures and cracks. Environmental protection and oil production
often use metallurgical microscopes and in particular they may
utilize both the high magnification and polarization features of
the metallurgical microscopes.
