Polarizing Microscope - Binocular Transmitted Light Microscope with Rotating Stage - 4X-100X, 6V/20W

The Master Science Polarizing Microscope is a transmitted-light instrument for studying birefringent specimens. A polarizer that turns through 360° sits below the stage and a sliding analyzer above the objectives, while the φ120 mm circular stage rotates to bring the specimen into different orientations.

Wide-field eyepieces and achromatic objectives from 4X to 100X give the Master Science Polarizing Microscope a broad, sharp field of view. Light comes from a 6V/20W halogen lamp with adjustable brightness.

Common Problems This Microscope Solves

Polarized light work asks for things an ordinary microscope lacks.

• Specimen must be turned to see extinction:: the circular stage rotates under the objective.
• Analyzer needed only part of the time:: it slides in and out of the light path.
• Focus slips during long observation:: tension adjustment keeps it steady.
• Objective crashes into the slide:: spring-loaded 40X and 100X objectives and a limit lock guard against it.
