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

Optics

The microscope optics are infinity-corrected and free of internal stress. The image formed by the lens is true-to-life, free of reflections, high-contrast and detailed. The lens is installed in a revolving nosepiece with slots centered on the optical axis. There are five slots, with four objectives included in the kit; an additional objective can be installed to provide further magnification within the microscope's magnification range. The objectives are designed for use with samples without cover slips.

The trinocular head allows a digital camera (not included) to be installed in the trinocular tube. The beam split is 100:0 or 0:100, meaning all 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 differences in vision between the eyes and to obtain the clearest possible image of the sample.

Illumination

30 W halogen lamps are used for transmitted and reflected light. Their brightness is sufficient to obtain a clearly legible image with each objective, and the “warm” emission spectrum is comfortable during extended use. Setting up Köhler illumination provides higher resolution and removes artifacts in the field of view and darkening at the edges. Light filters are used to fine-tune color reproduction when working with 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. The relative position of the analyzer and polarizer is then changed by rotating them, which also changes the polarization angle. The contrast of objects is increased with the help of compensators installed in a special slot in the intermediate tube. The same attachment also contains a Bertrand lens, which is used for conoscopic examinations.

Stage and focusing mechanism

The microscope has a rotatable stage: rotating it changes how the sample refracts light under polarized light. The stage has a scale that allows the rotation angle to be determined with a precision of up to 0.1°. To obtain the brightest and clearest image, the stage can be centered on the microscope's optical axis.

The coarse and fine focus knobs are located at the bottom of the stand, allowing the user to adopt a relaxed posture with their hands on the table. Coarse tension can be adjusted, and a coarse focus lock is also provided. Fine focusing ensures smooth movement of the sample.
