Filters are optical components that attenuate light intensity, alter spectral composition, or restrict the orientation of vibrations.
As commonly used accessories in photochemical experiments, they are made by depositing different film materials on glass or quartz substrates to achieve the desired filtering effect. Attenuation filters are capable of reducing the energy within specific spectral ranges. Full spectrum attenuation filters are employed to reduce the intensity of xenon lamp light sources across the entire spectrum, often used to attenuate the output energy of xenon lamp sources to mimic the intensity of sunlight.
There are two common models, namely 25% attenuation filters and 50% attenuation filters, with the numbers representing the percentage of output energy to the total energy.
Infrared region attenuation filters only filter out energy in the infrared region and are commonly used to eliminate the thermal effects of xenon lamps, with the model being broadband infrared attenuation filters.
If you need filters with other attenuation levels or attenuation in other optical regions, you can call 400-1161-365 for customization consultation.
