MB-207 40x-1000x LED Bino - a reliable laboratory microscope with achromatic lenses and glasses, two-stage focusing system, LED lighting and mechanized subject table. This is the case when it is difficult to determine what to consider the main advantage of the model: the quality of optics, precision mechanics or lighting capabilities. The microscope kit comes with 4 parfocal achromatic lenses and a pair of anti-glare Kellner glasses. The glasses are three-element, consisting of a lens doublet-gluing and a biconvex field lens: this scheme allows the eyepiece to enlarge the image constructed by the lens, without adding chromatic distortion. The field of view of the microscope, even in the 1000-fold magnification mode, is quite comfortable for long-term research. The Sigeta MB-207 40x-1000x eyepiece head rotates freely in any direction, and the force of its pressure on the landing platform can be reduced or increased by a clamping screw. The center-to-center distance of the binocular is regulated by the displacement of the ocular tubes, which rotate around a common support shaft; adjustment range - from 4.8 to 7.5 cm.
All control elements of the device (focusing drums, mechanical caliper handles, condenser adjustment screw, binocular centering system) instantly respond to touch, rotate smoothly and are clearly fixed in the selected position. For convenience of fine focusing on the rim of the microscrew handle there is a scale 0… 400 μm. The movable elements of the stage are equipped with verniers: this provides a more accurate, micrometric centering of the sample under the lens.
An adjustable light field capacitor is fixed under the sample platform, the aperture number of which, NA1.25, corresponds to a hundredfold lens. Therefore, even when working with immersion by adjusting the lighting system, you can achieve maximum image quality. Powerful LED lighting is based on modern S-LED technology. The illuminator is equipped with a dimmer, which implements stepless adjustment of the intensity of illumination. LEDs are powered in two ways: from the mains and from the built-in battery. With this microscope, the requirements for the workplace are significantly simplified, because it is not necessary to have access to an electrical outlet or a bright source of external lighting.
Among the purely operational characteristics of the MB-207 40x-1000x LED Bino microscope is a stable housing with a cast metal frame, reliable fixation of the binocular nozzle and undamaged powder coating.
