Typical optical path of spectrometer:

When the incident light is reflected by a mirror on the surface of the object being measured, it enters the spectrometer through the reflection probe. If the light intensity is too high, a reflective integrating sphere can be used for uniform reflection so that the light intensity at any point on the inner wall of the integrating sphere is the same. If you need to test the diffuse reflection performance of the object surface, you should also use a reflective integrating sphere.

Transmittance measurement optical path

Transmittance refers to the ratio of the intensity of light to the intensity of incident light when it passes through a material. Fiber optic spectrometers can accurately measure transmittance at different wavelengths by comparing the changes in light intensity before and after the lens. The transmittance curve reflects the ability of an optical lens to transmit light of different wavelengths and is one of the important indicators for evaluating the optical performance of a lens.

Liquid absorbance measurement optical path

Absorbance Measurement Principle:

According to Beer-Lambert's Law, chemical components in a solution or gas absorb light quantitatively. Absorbance is directly proportional to the molar absorption coefficient, path length, and concentration of the medium.

Using array detectors for UV/Visible/Near-Infrared spectral analysis is ideal for detecting large quantities of samples in industrial production. Absorbance measurement can be conducted by using different experimental setups and spectrometers with various wavelength ranges (e.g., immersion fiber probes, flow cells, or glass cuvettes), combined with light sources (such as deuterium lamps or deuterium-tungsten integrated light sources).
