Description
Известны интерференционные теплофильтры, содержащие чередующиес слои веществ с высоким и низким показател ми преломлени .Interference heat filters are known that contain alternating layers of substances with high and low refractive indices.
Предлагаемый теплофильтр отличаетс от известных устройств тем, что указанные слои прилегают к внутренним поверхност м двух стекл нных пластин, разделенных воздушным промежутком. Такое выполнение фильтра позвол ет расширить спектральную полосу отражени тепловых лучей.The proposed heat filter differs from the known devices in that the said layers are adjacent to the inner surfaces of the two glass plates separated by an air gap. Such an embodiment of the filter allows to expand the spectral band of reflection of heat rays.
На фиг. 1 и2 изображена схема предлагаемого теплофильтра в двух вариантах исполнени .FIG. 1 and 2 the scheme of the proposed heat filter in two versions is shown.
Теплофильтр состоит из двух интерференционных систем } и 2 (фиг. 1), представл ющих собой пленки, нанесенные в вакууме путем испарени чередующихс между собой слоев веществ с высоким и низким показател ми преломлени . Эти две интерференционные системы, разделенные воздушным промежутком 3, нанос тс на внутренние поверхности двух стекл нных пластин 4 и 5, наружные поверхности которых покрыты просветленным слоем 6 и 7.The heat filter consists of two interference systems} and 2 (Fig. 1), which are films deposited in vacuum by evaporating alternating layers of substances with high and low refractive indices. These two interference systems, separated by an air gap 3, are applied to the inner surfaces of two glass plates 4 and 5, the outer surfaces of which are coated with a coated layer 6 and 7.
Во втором варианте (фиг. 2) интерференционные системы / и 2 нанесены с двух сторон одной стекл нной пластины 8, причем наружные слои каждой системы состо т из термически и механически стойких покрытий 9 и 10.In the second embodiment (Fig. 2), the interference systems / and 2 are deposited on both sides of one glass plate 8, the outer layers of each system consisting of thermally and mechanically resistant coatings 9 and 10.
