Description
BK-POL series polarizing microscope is also named mineralogical microscope. It is necessary for researching double refraction sample, which is widely used in geology, mineral, chemical industry, medical, drug, criminal investigation fields, etc.
| Features of BK-POL Series Polarizing Microscope
- A professional binocular head can keep the cross in the right-hand eyepiece always the same when the eyepiece tubes are turned.
- Analyzer unit: 360° rotatable analyzer with division, can be locked and moved out of the light path.
- Bertrand lens, Built-in, focus adjustable.
- 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 users to avoid objective hitting.
- Compensator: Quartz wedge, First class red slip, λ/4 slip.
- Swing-out condenser: Swing the lens in to get an excellent image when using power objective to make observations.
| Objective Specification:（”●” is standard outfits, “○” is optional accessories.）
- “T” means transmitting “R” means reflecting
- “T&R “ means transmitting and reflecting

| Packing & Delivery
Polarizing series microscopes are packed in standard cartons. Except for the slightly smaller carton of the transmission polarizer, the other two models are large cartons, because polarizer accessories need to be placed inside. There are various modes of transportation, you can communicate with us in detail according to your needs.
