MAGUS Pol 850 Polarizing Microscope

The MAGUS Pol 850 Polarizing Microscope is designed to work in transmitted and reflected light. Available research methods: polarization and brightfield. The microscope is used to study anisotropic biological, geological, and polymer objects as well as opaque polished sections up to 15mm thick with one polished side. The microscope is perfect for a wide range of tasks of professionals in the field of medicine, forensics, mineralogy, crystallography, or petrography.

Optics

The optics of the microscope are infinity corrected and are free from internal strains. The image formed by the lenses is authentic, free of spurious reflections, high contrast, and detailed. The lenses are installed in a revolving nosepiece with slots centered to the optical axis. There are five slots, with four objectives included in the kit; one additional objective can be installed to obtain further magnification within the magnification range of the microscope. Objectives are designed to work with samples without cover slips.

The trinocular head enables you to install a digital camera (not included) in the trinocular tube. The beam splitting is 100:0 or 0:100, i.e., all of the light goes either to the camera or to the eyepiece tubes. The left eyepiece tube has a diopter adjustment ring: It is rotated to compensate for the difference in vision between the eyes and to obtain the clearest possible image of the sample.

Illumination

30W halogen bulbs are used for transmitted and reflected light. Their brightness is sufficient to obtain a clearly readable image on each objective, and the “warm” emission spectrum is comfortable during long-term use. Köhler illumination setup will provide increased resolution, and it will remove artifacts in the field of view and darkening at the edges. Light filters are used to accurately adjust color reproduction when working in reflected light.

Polarization is available for both transmitted and reflected light. To begin observations in polarized light, an analyzer is introduced into the optical path. Next, the relative position of the analyzer and polarizer is changed by rotating them, which also changes the polarization angle. The contrast of objects is increased with the help of compensators, which are installed in a special slot in the intermediate attachment. The same attachment also contains a Bertrand lens that is used for conoscopic examinations.

Stage and focusing mechanism

The microscope has a rotatable stage: Turning it changes the way the sample refracts light in polarized light. The stage has a scale on which you can determine the angle of rotation with an accuracy of up to 0.1°. To obtain the brightest and clearest image, the stage can be centered relative to the optical axis of the microscope.

The coarse and fine focusing knobs are located at the bottom of the stand, and so the user may take a relaxed pose with their hands on the table. The coarse tension can be adjusted, and there is also a coarse focusing lock. The fine focusing provides for the smooth movement of the sample.
