MB-302 40x-1600x LED Trino is a biological microscope with two eyepiece tubes and an additional optical port for a digital camera. Designed for clinical laboratory diagnostics, study of morphological changes in plant and animal tissues, as well as photo and video recording of experimental results (camera purchased separately).
accuracy of mechanical components. If necessary, the instrument can be equipped with accessories for dark-field and other types of optical microscopy. The set includes 4 achromatic lenses with high light transmission (with multi-layer illumination) and 2 pairs of glasses of different multiplicity. Illumination and anti-glare coating are also applied to the optical surfaces of the glasses. All surfaces of the microscope that are likely to come into contact with liquids or fragments of the drug are treated with an antifungal agent.
The trinocular head of the microscope rotates freely on a horizontal base. The distance between the tubes of the binocular nozzle is adjustable manually: for this purpose at the end of the central shaft there is a marking indicating the wheelbase in millimeters (from 54 to 75 mm). . The focal length is adjusted by moving the stage, while the optical unit remains stationary. The two-sided control unit of the macro- and microscrew mechanisms consists of coaxial knobs of coarse and fine focusing. The table screw limiter is designed to fix the safe distance between the lens and the cover glass when focusing at high magnifications. they are controlled by rotating coaxial handles. The tabletop has a stain and scratch-resistant soft-touch coating: micrometer calipers move the slide smoothly, effortlessly, placing the sample under the lens. Slide range - 7.2 x 3 cm, tabletop dimensions - 12.5 x 11.5 cm.
The lighting system of the microscope consists of a 1-watt LED lamp, aspherical collector and classic Abbe condenser with multi-petal aperture diaphragm and light filter holder. Moving the aperture slider changes the size of its aperture: adjusting the diameter can affect the brightness and contrast of the image visible in the eyepiece. Due to this, when working with different combinations of glasses and lenses, you can get a contrasting and bright image across the field of view.
