Polarizing Microscopes for Geology & Crystallography
Murzider Polarizing Microscopes are purpose-built analytical instruments tailored for geological analysis, mineral identification, and crystallography research.
Equipped with professional polarization optical components and precision mechanical structures, our polarizing microscopes deliver reliable crystal imaging and mineral section analysis, helping labs and research institutions achieve accurate material identification and structural characterization.
- High-precision polarization system for mineral & crystal structural identification
- 360° graduated rotating stage for accurate angle measurement & observation
- Strain-free optical lenses ensure true birefringence presentation
- Dual transmitted and reflected light adapts to rock slices and crystal samples
- Clear interference imaging for mineral texture and internal structure analysis
- Diversified tube configurations support manual observation and data recording
Working Principle
Murzider polarizing microscopes operate based on light polarization and birefringence principles:
1. Unpolarized light passes through a polarizer to become plane-polarized light
2. Polarized light enters the anisotropic specimen and splits into two rays (double refraction)
3. Two rays travel at different speeds, creating a phase difference
4. Rotatable analyzer (second polarizer) filters the light after the sample
5. Interference occurs, producing vivid interference colors specific to each material
6. 360° stage rotation reveals extinction angles and optical sign of minerals
7. Bertrand lens enables conoscopic observation of interference figures for crystal identification
Key Components
Polarizer & Analyzer
High-extinction-ratio polarizing filters (crossed at 90°) generate and analyze polarized light for maximum contrast.
360° Rotating Stage
Precision mechanical stage with 0.1° graduations for accurate extinction angle measurement and crystal orientation.
Strain-Free Objectives
Special plan-achromatic objectives eliminate internal birefringence, ensuring accurate interference color observation.
Bertrand Lens
Conoscopic lens for viewing interference figures, critical for mineral optic sign and crystal system identification.
Compensator Plates
Quarter-wave, full-wave and mica plates for quantitative birefringence and optical path difference analysis.
LED Illumination
Uniform, dimmable transmitted/reflected LED light for consistent color temperature and long-hour observation.
