Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] First describe the material, shape and structure of each part of the present invention:

[0021] a. Electrothermal constant temperature light hole 1 without thermal insulation window, to ensure that weak laser light or photon pulse sequence can pass through without light loss. The hole contains ribbing and blackening treatment to increase the thermal area and thermal efficiency; the diameter of the hole is consistent with the size of the weak laser or photon beam working (through light).

[0022] b. Heating wire 2, thermal gradient non-uniform winding structure (armoured double core single winding, armored single core double winding, heating wire double winding).

[0023] c. The holding furnace 3 is made of polytetrafluoroethylene plastic material, which produces a suitable sample (alkali metal atom) density and ensures (atomic or molecular spectral l...

Abstract

The opened electrothermal constant-temperature optical window consists of heating filament, heat insulating furnace and metal skeleton. The metal skeleton has one end connected directly to the inside of the heat insulating furnace and the other end serving as the heat radiating end; the heating filament is wound directly around the metal skeleton; and there is one heating air output passage between the metal skeleton and the heat insulating furnace. The present invention has simple structure, convenient use, and integrated functions of passing light, heating and maintaining constant temperature. The present invention may be used singly or in pair to raise the performance of atomic vapor or molecular gas optical filter device, and is suitable for use in weak laser and fluorescence condition, especially in single proton detecting level.

Description

technical field [0001] The present invention relates to the field of optics and radio electronics, and more specifically relates to an open electrothermal constant temperature optical window. The device of the present invention replaces traditional insulating glass or optical windows of other materials, and can greatly improve the efficiency of atomic vapor or molecular gas filter devices. Performance, so that the relevant working parameters are improved, the transmittance of the device is increased, and the filter efficiency of the device is improved, so as to ensure that the entire application system (such as communication, radar, scientific experiments, etc.) can work well. The present invention is suitable for use under weak laser and fluorescent conditions, especially at the single-photon detection level. Background technique [0002] Devices designed using alkali metal atomic vapors and molecular gases such as iodine have found applica...
