Inclined Monocular Polarising Microscope (PM - 10)

The PM-10 Student Polarizing Microscope is developed for instructional laboratories conducting polarized light analysis. It combines a rigid mechanical frame with a complete polarizing optical system for reliable observation. The monocular head supports Bertrand lens use, while a precision rotating stage, coaxial focusing, adjustable condenser, and built-in halogen illumination provide controlled, repeatable conditions for mineralogical and crystallographic training applications within standard educational microscopy curricula and routine laboratory practical sessions worldwide.

Working Principle

 

The PM-10 Polarizing Microscope functions by passing light from the built-in halogen source through a graduated polarizer to generate plane-polarized light. When this light interacts with anisotropic specimens on the rotatable stage, it undergoes birefringence. The sliding analyzer recombines the light components, producing observable interference effects. Stage rotation, compensators, and condenser adjustments enable systematic examination of optical properties under controlled illumination.
