The MAGUS Pol 800 Polarizing Microscope is used to study anisotropic objects in polarized and ordinary transmitted light. Objects of study can be biological, geological, or polymer. The optics of the microscope are strain-free, i.e., they do not create parasitic refractions. They form a clear, high-contrast and authentic image. The microscope’s functionality is useful in various fields of science: medicine, forensics, mineralogy, petrography, crystallography, etc.


The trinocular head is equipped with a trinocular tube for mounting a digital camera (camera not included). By using the switch on the body, the light is completely directed either to the eyepiece tubes or to the digital camera. The 30° angle of the eyepiece tubes is comfortable for long-term observations and does not cause strain on the neck muscles. The left tube has a diopter adjustment ring in which it rotates and adapts the optics of the microscope to the user’s unique vision.

The revolving nosepiece is designed for the simultaneous installation of five objectives, with four already included in the package. An additional objective from the MAGUS range of accessories can be purchased separately. All of the objectives are designed to work with 0.17mm thick cover slips. Thanks to the “away from the observer” revolver design, the objective inserted into the optical path is clearly visible during work, which makes the researcher’s work more convenient. The revolver nosepiece slots are centered.


The illumination source is located under the object stage, i.e., observations are carried out in transmitted light. The 30W halogen bulb produces bright, eye-friendly illumination that is suitable for use on all objectives. Adjusting the illumination using the Köhler method achieves higher contrast and enhanced image quality.

The microscope is equipped with a polarizer and analyzer. To work in polarized light, the analyzer is introduced into the optical path, and the polarization angle is changed by rotating the polarizer and analyzer relative to each other. The microscope also has an intermediate attachment that holds a Bertrand lens and has a slot for compensators. Compensators enhance the contrast of samples with low birefringence, and the Bertrand lens is designed for conoscopic studies.

Stage and focusing mechanism

The microscope stage rotates and that enables you to quickly change the refraction of light by the sample when working in polarized light. The stage is centered relative to the optical axis of the microscope, has rotation angle gradation and a scale that enables you to determine the angle with an accuracy of 0.1°.

The focusing mechanism provides coarse and fine sharpness adjustment. For coarse focusing, a coarse focusing lock is available, and you can also adjust the coarse tension for the most comfortable control.


Optional eyepieces, objectives, digital cameras, and calibration slides are available for the microscope. They broaden the capabilities of the microscope for carrying out researchers’ tasks.
