What is the advantage of minitaure spectrometer?

Traditional spectrometers use wavelength scanning mechanism for scanning, volume is large and expensive. Compared with this, the micro-optical fiber spectrometer has many advantages, such as fast speed, low price, small volume, light weight and full spectrum acquisition, and can be measured out of the sample room through optical fiber conduction, suitable for online real-time detection.

How to measure absorbance quantitatively?

Absorbance spectrometer can be used to qualitatively identify "fingerprint" substances or quantitatively measure the concentration of colored substances (hair color subgroups) in transparent solutions. In some cases, it is necessary to know the absolute absorbance or extinction coefficient of the unknown substance. In other cases, the concentration of the unknown relative to the known concentration of the standard solution can be determined by the formula. In both cases, the derivation of absorbance is known as Beer-Lambert's law.

How to detect absorbance?

Absorbance refers to the log base 10 (namely LG (I0/I1) of the ratio of the incident light intensity before the light passes through the solution or substance to the transmitted light intensity after the light passes through the solution or substance, where I0 is the incident light intensity and I1 is the transmitted light intensity, and the factors affecting it include solvent, concentration, temperature and so on.
