Product Description

Introduction

BS-5095 series scientific research polarizing microscopes have been specially designed for laboratory and scientific research work and university education, the microscopes combine with the practical, easy operation and superior optical system, can be used for single polarization, orthogonal polarization, conoscopic light observation. They can provide you reliable, high resolution and high contrast image. The microscopes can be used for multipurpose polarized light observation in fields such as geology, mineralogy and fossil fuel resource exploration.

Feature

1. Research-grade Polarizing Microscope with Wide Application Range and High Reliability.
(1) Transmission observation: Bright Field, Dark Field, Phase Contrast.
(2) Reflection observation: Bright Field, Dark Field, Polarizing, Fluorescent, Phase Contrast (DIC).
(3) Multiple Types of Compensators are available.
2. Excellent Optical Quality and Strong Stability.
(1) Infinite optical system and 10X/25mm eyepiece provide a high definition and wide view field.
(2) Kohler Illumination System with Uniform Illumination makes the microscopic imaging more realistic and the results are highly repeatable.
(3) Strain-free Plan objectives Make Imaging More Accurate.
(4) Center Adjustable Sextuple Nosepiece allow more objectives.
(5) High-precision Revolving Round Stage, diameter 190mm, pre-centered, attachable X-Y stage is optional.
(6) The polarizing set includes 0-360° rotatable analyzer, Bertrand lens can switch very quickly from conoscopic and orthoscopic images.
(7) Compensator Slot on nosepiece. Various compensators can be used to enhance the advanced quantitative measurement of the signal of the weak birefringent material.
3. Tilting Seidentopf Trinocular Viewing Head can be operated in a more comfortable position.
4. Rotary Observation Module. Up to 6 observation modules can be placed in the rotating disc structure, different observation method can be quickly switched.
5. ECO Function. The transmitted light would be off automatically after 30 minutes from operators leave. It can save energy and extend the lamp life.

Application

BS-5095 series polarizing microscopes are ideal instrument in geology, petroleum, coal, mineral, chemicals, semiconductor and pharmaceutical inspection fields. They are widely used in academic demonstration and scientific research areas.
