Simple polarizing microscope--use and maintenance

1. Purpose of simple polarizing microscope:

XSP-10 simple polarizing microscope is a dual-purpose use of polarimeter and microscope after adding a set of components on the basis of biological microscope. XSP-10 microscope is one of the most versatile optical instruments. It uses microscopic magnification technology of optical principles to make specimens of collected fine samples, magnify and observe the microscopic technology, and can also be used for polarized light principle detection. The instrument of the birefringence effect of the sample, therefore, the instrument is widely used in biology, anatomy, bacteriology, histology, pharmacology, biochemistry, neurology, osteopathy, physiology, serology, virology, urology, etc. Subjects can be used for clinical trials and routine tests in medical treatment; for teaching in school laboratories.
