Transmittance

Spectral transmittance is the ratio of the radiation luminous flux emitted from the optical system to the radiation luminous flux projected to the optical system, which reflects the reference standard of the radiation luminous flux loss of the whole optical system. The measurement of spectral transmittance of transparent and semi-transparent objects (including liquid, glass, etc.) has great practical significance and application value, such as evaluating the quality of filters according to their spectral transmittance; glass transmittance is an important index for detecting whether the glass is qualified or not; detecting the transparency of liquids in medical and health, industrial production, chemical synthesis and other fields.

Compared with the traditional experimental determination of transmittance, the spectral kit built with the spectrometer as the core, its test is simple and efficient, and the experimental results are accurate and reliable, so that researchers are free from complicated experimental operations and human errors are reduced. At the same time, the equipment layout can be changed according to changing experimental needs; the constantly upgraded experimental operations and applications make a variety of experimental applications possible now and in the future.
