SIGETA MB-140 40x-1000x

SIGETA MB-140 40x-1000x is a school-level school microscope designed to study microsamples in transmitted, reflected and mixed light. The most important features of the model are achromatic lenses, two-stage focusing, LED lighting, mechanical slide shifter and two types of power supply (stand-alone and mains-operated). in conjunction [eyepiece 25x + "dry" lens 40x], ie without the use of immersion. Of course, the detail of the picture will be poorer than in the case of [10x eyepiece + 100x lens (oil)], but the user will not need the skills to work with immersion fluid and the ability to perfectly adjust the lighting system. 1000x large enough - 9.5 x 9.5 cm, has a smooth matte surface, along which the slides move smoothly, without slipping and jerks. "Out of the box" the table is equipped with two clamps: they are convenient to use when studying in the reflected light of thin dimensional samples, such as leaves, banknotes, pieces of fabric, etc. However, removable micrometer calipers are also included: they are easy to install and secure to the table with a screwdriver. Macro and microfocus knobs are coaxially mounted on both sides of the body, convenient to rotate with the thumb and forefinger of one hand. The illuminator is connected to the microscope via a USB connector and does not have a separate intensity control. Both LED lamps can work separately or together, creating mixed lighting to study samples of medium transparency. A ring diaphragm with holes of different diameters is mounted under the stage to vary the size of the light spot. biology.
