Optical filter

Product classification:filter brand:perfectlight view count:4228

Filters are optical parts that can attenuate the light intensity, change the spectral components or limit the plane vibration. They are mainly made by glass or quartz substrates, plated with different membrane materials to achieve the corresponding filter effect. They are accessories commonly used in photocatalytic experiments. In the photochemical research field, filters are divided into transmission/reflection filter, cut-off filter, band-pass filter, and desired radiation band could be obtained by integrating filters of different types.


All series filters (Beijing Perfectlight Technology Co., Ltd.) are made with quartz material, the cut-off rate of the cut-off filter is as high as 99.5% or more, transmittance of the bandpass filter at the visible zone is higher than 85%. Filters are made by Germany Coating equipment and technology, have a very low wavelength thermal drift and extremely low time wavelength drift performance. And spectrum measurement services are available for all series filters with light source before delivery.
