Visible Light SpectroMeter

A visible spectrophotometer uses a prism or grating to separate the light source into monochromatic light, causing the sample to absorb light at specific wavelengths, and the detector measures the intensity of the transmitted light. It is used to determine solution concentrations and substance content, as well as to detect dye components or pollutants in the chemical and environmental protection fields.
Selection
When selecting, consider a wavelength range covering 380-780 nm, with bandwidth matching the detection accuracy requirements. Pay attention to baseline stability and stray light indicators. The sample chamber should be compatible with test tubes or cuvette specifications. The operation interface should be simple and intuitive, and the system should come with calibration tools and maintenance guidelines.
