Research Polarizing Microscope - Trinocular Reflected and Transmitted Light - 5X-60X, 6V/30W Halogen

The Master Science Research Polarizing Microscope uses an infinity optical system in a modular stand that carries both an epi-illumination system and transmitted illumination. Its objectives are infinity-corrected, strain-free and long working distance, which is what polarized light measurement requires.

A push-in Bertrand lens, three compensators and a graduated rotating stage with 6′ vernier make the Master Science Research Polarizing Microscope suitable for research and inspection in geology, chemical engineering, medicine and pharmaceuticals. It also handles crystal phase observation of liquid polymer materials, biopolymers and liquid crystal materials.

Common Problems This Microscope Solves

Serious polarized light work exposes the limits of a basic stand.

• Lens strain adds false birefringence:: strain-free objectives keep the background clean.
• Interference figures cannot be seen:: a Bertrand lens pushes into the path when needed.
• Retardation is hard to judge:: gypsum, mica and quartz wedge compensators are provided.
• Dim images are difficult to photograph:: the 0:100 setting directs all light to the camera port.
