Liquid transmission measurement using the optical fiber spectrometer

GLit transmission spectrum is a kind of spectrum that appears after light passes through a sample. By measuring the transmission spectrum of a sample, it characterizes some properties of the sample. It is widely used in scientific research and industry.
The transmission spectrum measurement is divided into a liquid transmission measurement and a solid transmission measurement depending on the morphology of the sample to be measured.

This is a liquid item test chart:

The above liquid transmission spectrum measurement map is that the light emitted by the light source is irradiated on the sample through the silica fiber, and the light transmitted through the sample is transmitted to the fiber optic spectrometer via the optical fiber, and the photoelectric conversion is performed to represent the spectrum. In this measurement chart, the light source can switch between the halogen light source and the LED light source to meet different experimental requirements.
