BK-POL Series Polarizing Microscope

  Performance characteristics:

Also named mineralogical microscope, is necessary for researching double refraction sample, which is widely used in geology, mineral, chemical industry, medical, drug, criminal investigation fields etc.

● Professional binocular head can keep the cross in the right-hand eyepiece always same when the eyepiece tubes turned.

● Analyzer unit : 360° rotatable analyzer with division, can be locked and moved out of the light path.

● Centering nosepiece, non-stress infinity plan objective.


● Rotatable 360° stage , division 1°, vernier division 6’, adjustable center which can be locked.

● Polarizing unit:  rotatable 360°, scaled, can be locked.

● Attached polarizing mechanical stage: professional design for laboratory’s user to avoid objective hitting.

● Compensator: Quartz wedge, First class red slip, λ/4 slip.

● Swing-out condenser, Swing the lens in to get excellent image when using high power objective to make observation.
