Examination of samples with light microscopy reveals critical information using a variety of magnifications, and illumination configurations. |
Optical Microscopy Utilizing Polarized Light |
|
Polarized light microscopy (PLM) is a powerful and flexible technique for the examination of small particles such as pigment particles, mineral grains, fibers, environmental particulate, and biological materials. Light microscopy has been used for many decades to characterize particles down to the micrometer size scale. |
|
> PLM Applications > For Pigment Analysis - PLM provides refractive index, particle size, size distribution, color, shape, pleochroism, optical properties, and morphology data which are critical for the identification of the type of pigment and its source. > For Fiber Analysis—PLM reveals surface characteristics, fiber diameter and optical properties such as refractive index and birefringence that can discriminate fibers that are identical chemically, but have morphological differences.
