pls-lf liquid filter is usually used for xenon lamp light source or the light source of strong infrared radiation output to filter the infrared radiation light and avoid the interference of infrared light to the test. the inside of the cavity is light filter, which can exchange heat with the shell. therefore, low-temperature window materials can be selected. the use of independent fin heat dissipation, to avoid the use of fluid heat transfer inconvenience. in the cavity of the filter fluid, can choose different liquid, such as pure water, acid and alkali solution and inorganic salt solution; the optical windows can also be made of materials with different optical properties, such as quartz and high borosilicate glass, etc., so as to change the transmittance characteristics of the liquid filter and meet the requirements of different tests.
the pls-lf liquid filter can completely remove infrared spectrum. in general, starting from about 1 living meter, it can effectively remove even 10 living meters (under sufficient heat dissipation condition). in combination with light window and light filter, it can also filter out the light radiation of characteristic bands, such as visible near-infrared light and ultraviolet light.
the liquid filter can effectively filter the near, middle and far infrared light and output the ultraviolet visible light, which can be regarded as the "cold light source". the thermal influence of infrared light on photocatalytic reaction can be greatly reduced, for example, the influence of infrared light on photocatalytic hydrogen production test can be avoided.
liquid filters with different bandpass filters can effectively improve the stability of the filter and reduce the influence of temperature on the performance of the filter.
