CONTAINER FOR OPTICAL-ELECTRONIC DEVICES Russian patent published in 2021 - IPC B65D85/38 B65D81/20 G12B9/02 H05K5/02 G12B7/00 H05K7/20 

FIELD: optical instrumentation.

SUBSTANCE: invention relates to optical instrumentation, in particular to devices for protecting the optical path of optoelectronic devices and systems from the influence of thermal disturbances. The declared container for optoelectronic devices, containing filled with a gaseous medium with a thermal conductivity of at least 0.05 W/(m °K), the dew point of which is not higher than - 50°С, a sealed housing with at least one window, with a fitting, a temperature sensor, communication unit and control unit. The novelty is that in the device the body and the fitting are made of metal and are separated by an electrical insulating sleeve, the control unit is made in the form of a tracking system containing a medium immitance meter with a power source, a computing device with memory and a timer. In this case, one input of the immitance meter of the medium is electrically connected to the body, the second - to the fitting, the outputs of the immitance meter and the temperature sensor are connected to the computing device, and the gaseous medium is selected from the condition (c₁ρ₁+c₂ρ₂+…+c_nρ_n)≤934.2 J/(m³ °K), where ci is the specific heat capacity of the gas medium component, J/(kg °K); ρ_i is the density of the component of the gaseous medium, kg/m³; n is the number of components of the gaseous medium.

EFFECT: improving the efficiency and accuracy of measurements.
