Infinity Optic System Digital Metallurgical Microscope with DIC and LED Illumination
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.
