Polarising Microscopes

Specialised in optical microscopy, polarising microscopes utilise polarised light properties for the analysis and observation of physical characteristics in specimens. Widely employed in geology, mineralogy, metallurgy, and biology, these microscopes facilitate the study of internal structures and compositions of various materials.

The Standard Microscope Model stands out as a sophisticated instrument, featuring top-tier components. Equipped with infinity optics, a trinocular head, and high-quality objectives offering a magnification range of 40X to 600X (with an optional extension up to 1000X), this model also includes a measurement reticle in one of the eyepieces for precise centring, along with a focus adjustment mechanism for added convenience.

This model boasts exceptional polarisers, ensuring outstanding extinction results when using crossed polars. The fully corrected optics prevent colour changes during adjustments in viewing angles, providing a consistent viewing experience. Additionally, an adjustable condenser with 30W illumination sources, Koehler illumination, and coarse/fine focus knobs featuring limit stoppers and tension adjustment enhance the microscope's functionality. The robust frame ensures stability, making it ideal for photomicrography.

Our collection of Polarising Microscopes caters to diverse needs, offering transmitted light, incident light, and dual-illuminated models. Advanced models feature cutting-edge elements such as waveplate inserts and Bertrand lenses, enabling in-depth analyses like conoscopy for highly accurate results. These microscopes empower users across various disciplines to conduct sophisticated studies with confidence.

Principles of Polarising Microscopy

Polarised light, oscillating in a single plane, is employed in polarising microscopes. A polariser generates polarised light directed toward the specimen, and the light passing through is analysed by a second polariser, the analyser. Manipulating the orientation of these elements allows for determining the optical properties of the specimen, such as birefringence and optical axis.

Components of a Polarising Microscope

A polarising microscope typically consists of the following components:

  1. Polariser: Produces polarised light
  2. Specimen stage: Platform for mounting the specimen
  3. Eyepiece: Magnifies the image for observation
  4. Objective lens: Forms an image of the specimen
  5. Analyser: Second polariser analysing light passing through the specimen
  6. Bright field illumination: Light source illuminating the specimen
  7. Bertrand lens: Observes crystal form and determines the optical axis
