Phase contrast device Micromed 3 U
Phase contrast device Micromed 3 U. The PKU phase contrast observation device is designed for studying low-contrast objects that are not visible in microscopes under normal observation conditions. The device can be used in conjunction with biological microscopes Microhoney 3 (U 2) and Microhoney 3 (U 3). The main parts of the device are a phase condenser, phase objectives and an auxiliary microscope. Dovetail phase condenser mount. The kit includes planachromatic phase lenses. The objectives are designed for a tube length of "infinity" and a cover glass thickness of 0.17 mm. The operating principle of the device is based on the phase contrast method, which makes it possible to observe unstained low-contrast preparations. The condenser can be used for observation in the usual way; For this purpose, there is an iris diaphragm under the revolver disk, and in the revolver disk, in addition to the annular diaphragms, there is a free hole for transmitting the entire beam of light. The phase condenser is inserted into the microscope's condenser bracket ring in place of a conventional bright-field condenser and is clamped with a screw in the usual manner. Changing the annular diaphragms, depending on the lens used, is done by turning the turret disk by the knurled part until it locks, and in the window of the condenser housing there should appear a number corresponding to the magnification of the lens used or the inscription “BF”, corresponding to a free hole for working in a bright field, or the inscription “DF” for working using the dark field method. An auxiliary microscope is used to center the image of the condenser annular diaphragm relative to the phase ring of the lens. Manba: https://www.nv-lab.ru/catalog_info.php?ID=6454
