Spectral transmittance is the ratio of the transmitted light intensity to the total light intensity, which reflects the reference standard for the radiant flux loss in the entire optical system. The spectral transmittance measurement of transparent, translucent objects (including liquids, glass, etc.) is of great significance and value.It is widely used in evaluating the quality of the filter. And it is also an important indicator of the qualified glass and liquid transparency testing in medical and health, industrial production, chemical synthesis and other fields.
For spectral transmittance measurement, a spectrometer, light source, fiber, measuring holder, standard reference sample, and measurement software are usually required. Brolight provides users with those testing equipment. With the configured devices, you can build a variety of common spectral measurement systems. Each of the measurement system has its applicable spectral range. Therefore, it is necessary for the users to select the appropriate spectral range. For example, in order to measure the UVspectrum, a spectrometer capable of detecting the ultraviolet wavelength and a broad spectral of ultraviolet radiation light source are required.
