Phase Contrast  
Phase Contrast Observation  

• The introduction of phase contrast has made human vision a new expansion. 

• Phase contrast observation with an inverted microscope can clearly observe transparent living samples, which are mostly used for cell culture. 

• Principle: The retention degree of light passing through substances of different densities is different (the higher the density, the longer the residence time)

 
   

 

       

 No phase contrast effect

Has phase contrast effect

   

Phase Contrast Plate

Phase contrast plate converts optical path difference or phase  difference into amplitude difference to enhance contrast. Light absorbing substances in the plate to enlarge the potential difference of deviated light, two light groups converge into a beam through the lens, the interference phenomenon of super position or cancellation occurs and show the visible light and dark difference.

 

Objectives and Eyepieces

Objectives

Application


Living tissue observation

Generally,small pieces of diseased tissues,body fluids,and cells of animals are obtained by 

surgical cutting,clamping,or scraping and aspiration.After pathological tissue or cytological 

methods are made into thin sections,the pathological diagnosis can be made by observing 
under a microscope.




Bio-pharmacy

Biopharmaceuticals are the research results of microbiology,biology,medicine,and biochemis-

try.A class of products used for prevention, treatment and diagnosis made from organ-isms,

 biological tissues, cells, organs, and body fluids using scientific principles and methods.




Medical diagnosis

Medical diagnosis is the examination of mate-rials taken from the human body. Through 

microbiology,immunology,biochemistry,genetics,hematology,biophysics, cytology, etc, 

provide information for the prevention, diagnosis, treatment of human diseases and 

assessment of human health.



Prevent disease

Conduct epidemiological monitoring of the occurrence, development and distribution of major 

diseases, and propose prevention and control countermeasures. Such as infectious diseases, 

parasitic diseases, chronic non-communicable  diseases, public hazards, food-borne diseases,

poisoning, etc.
