The Sigeta MB-203 40x-1600x professional binocular microscope is a high-quality optical device that creates a clear, sharp and detailed image with minimal optical distortion. The microscope is equipped with a binocular nozzle with the ability to rotate 360 ° and adjust the interpupillary distance in the range of 54 - 75 mm. The right and left spectacle tubes have built-in diopter correction to compensate for the difference in eye strength. The revolving lens holder is designed for four seats and has a rubber radial cover for easy rotation and change of lenses. The set includes 4 achromatic lenses (4x, 10x, 40x, 100x) and two pairs of wide-angle glasses (10x, 16x) with an illuminating coating. The subject table (14 x 15.5 cm) is equipped with a drug holder with a coaxial handle for moving the holder on racks. Under the stage is the Abbe 1.25 condenser with a petal diaphragm that adjusts the contrast of the image. The LED lamp with a cold color temperature is located inside the housing and is complemented by a removable lens collector (Ø 43 mm) with a matte finish. Also included is a mirror to reflect and direct light on the sample slide, which can be installed in place of the main lighting module, which gives this microscope autonomy and mobility of use. Another feature of this model is the focus adjustment, which is located in the assembly with coaxial handles of macro and micro screws: on the left side of the case, the ring adjusts the force of rotation of the coarse focus handle, while on the right - adjusts the maximum table. This is useful for laboratory work with constant changes of micropreparations, as it eliminates the possibility of damage to the slide with the sample. This laboratory tool will open new opportunities for detailed research of microobjects in the field of histology, cytology, bacteriology and other fields of science.
