Introduction

The BS-5040 transmitted polarizing microscopes are equipped with a smooth, rotating, graduated stage and a set of polarizers that allow observation of all types of transmitted light polarized specimens such as thin sections of minerals, polymers, crystals and particulates. It is equipped with an infinite optical system, a comfortable viewing head and a set of Strain-free Infinite Plan Objectives which offers a magnification range of 40X - 400X. Digital camera can be used together with BS-5040T for image analysis.
 

Features

1. Perfect optical system
Excellent infinite optical system with high resolution and perfect definition. High resolution and perfect definition from infinity correct optical system.

2. Infinity stain-free plan objective
Infinite strain-free plan objectives, ensuring excellent resolution and clarity.

3. Nosepiece and stage
Center adjustable nosepiece and rotating stage make the operation more accurate and reliable.

4. Viewing head
Brand new and humanized butterfly binocular head-tubes can be 360° rotated to raise observing height than normal tubes to be more convenient for users with different height.
 

5. Power supply
5V-12V low voltage input to ensure safe use.
Power bank can be used for power supply, more convenient for field inspection and power-short condition
 

 

Application

The BS-5040 series polarizing microscopes are specifically designed for geology, minerals, metallurgy, university teaching laboratories and other sectors. They also can be used in chemical fiber industry, semiconductor industry and the pharmaceutical inspection industry.
