The MAGUS Pol 850 polarizing microscope is designed to operate in transmitted and reflected light. Available research methods: polarization and bright field. The microscope is used to study anisotropic anibiological, geological and polymeric objects, as well as opaque polished sections up to 15 mm thick with a polished side. The microscope is perfect for a wide range of tasks of professionals in the fields of medicine, forensics, mineralogy, crystallography or petrography.
Digital camera
The MAGUS CBF70 professional scientific camera is designed for use with a microscope as well as 4x, 10x, 20x and 40x objectives. The device allows you to take photographs, shoot videos, organize demonstrations, display images on an external screen and perform angular and linear measurements of study objects (for this function to be performed correctly, the software must be calibrated). The camera is recommended for working with the bright field method.
The MAGUS CBF70 camera has five image resolution and frame rate modes, so among them you can easily find the one that best suits your needs. your needs: 5280x3954 px (17 fps), 3952x3952 px (17 fps), 2640x1976 px (56 fps), 1760x1316 px (67 fps) and 584x438 px (192 fps).
The high resolution modes are ideal for photography, allowing you to create clear, vibrant and highly detailed images. Modes with increased frame rate will help when recording smooth and informative video, without jumps and delays, recording the smallest movements of the object or features of fast processes observed.
To obtain the best image quality without distortions , it is recommended to use an adapter with 1x magnification.
The camera design uses a 4/3” color back-illuminated SONY Exmor CMOS sensor. It makes the image bright even in a low-light environment. The larger physical size of the sensor helps the colors displayed appear deeper and the image appear clearer.
Optics
The microscope's optics are corrected to infinity and are free from internal tensions. The image formed by the lens is authentic, glare-free, high-contrast and detailed. The lens is installed in a nosepiece with grooves centered on the optical axis. There are five grooves, with four lenses included in the kit; An additional objective can be installed to achieve further magnification within the magnification range of the microscope. The objectives are designed to work with specimens without coverslips.
The trinocular head allows you to install a digital camera in the trinocular tube. The beam split is 100:0 or 0:100, meaning all the light goes to the camera or eyepiece tubes. The left eyepiece tube is equipped with 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 specimen.
Illumination
strong>
30W halogen lamps are used for transmitted and reflected light. Their brightness is sufficient to obtain a clearly readable image on each lens, and the “warm” emission spectrum is comfortable during long-term use. The Köhler illumination setting will provide greater resolution and remove artifacts in the field of view and darkening at the edges. Light filters are used to fine-tune 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 installed in a special housing in the intermediate tube. The same attachment also contains a Bertrand lens which is used for Conopic examinations.
Stage and focusing mechanism
The microscope has a rotatable stage: rotating it changes how the sample refracts light in the presence of polarized light. The stage is equipped with a scale on which the angle of rotation can be determined with an accuracy of up to 0.1°. To get the brightest and clearest image, the stage can be centered on the optical axis of the microscope.
The coarse and fine focus knobs are located at the bottom of the stand, so the user can assume a relaxed pose with hands on the table. The coarse tension can be adjusted and there is also a coarse focus lock. The fine focus ensures smooth movement of the sample.
