FIELD: physics, control. ^ SUBSTANCE: invention is related to the field of physicotechnical tests and surveys of materials and is intended for automatic stabilisation of object temperature in the range of 4.2-350 K with accuracy of 0.02 K. The novelty in the device is combined thermostatted chamber and prechamber, which us arranged in the form of two hollow mutually perpendicular cylinders, besides external and internal ends of horizontal cylinder are plugged, creating two heat exchange chambers, which are connected to each other by four channels, which are arranged in pairs symmetrically to axis in body of vertical cylinder, and on the side surface of vertical cylinder there are electric heater and coil arranged, moreover, upper end of vertical cylinder is closed by gasket from transparent optic material, under which bushings and temperature detector are installed. Body is equipped with tapping installed perpendicular to body, in which chamber is arranged, being enveloped by radiation screen, besides screen and tapping have optical windows above transparent gasket of chamber. ^ EFFECT: creation of device design for its application in optical microscopy. ^ 3 dwg |
