Spectroscopic instruments work according to the dispersion components of the spectroscopic principle, spectroscopic instruments can be divided into: prism spectrometer, diffraction grating spectrometer and interference spectrometer.
Spectrometers are medical LEDs that are composed of 287 special medical SLDs that irradiate at 4 wavelengths: red (640nm), blue (423nm), green (532nm), and yellow (583nm).
1. "RED" Red ? - Wavelength 640nm Penetrates the skin 1~6mm: It has a good effect on skin cell regeneration, promoting blood circulation, relieving acne scars, allergic dermatitis, relieving pain, and activating active ingredients.
2, "BLUE" blue - wavelength 423nm penetrate the skin 1mm: for killing acne bacteria, inhibit sebaceous glands, preventing wound infection, calming the allergic skin has a good help.
3, "GREEN" green - wavelength 532nm penetrate the skin 0.5 ~ 2mm: for sensitive skin and the body and mind have a good calming effect.
4, "YELLOW" yellow - wavelength 583nm penetrate the skin 1 ~ 2mm: effective treatment of skin redness / erythema, relief of redness, pigmentation redness and other effects
Expanded Information:
Spectroscopic instruments can be divided into two main categories: classical spectroscopic instruments and new spectroscopic instruments. Classical spectroscopic instruments are instruments built on the principle of spatial dispersion; new spectroscopic instruments are instruments built on the principle of modulation. Classical spectroscopy instruments are all slit spectroscopy instruments. Modulation spectrometer is non-spatial dispersion, it uses a round hole into the light.
Spectrometers are used in a wide range of applications in agriculture, astronomy, automotive, biology, chemistry, coating, colorimetry, environmental testing, thin film industry, food, printing, paper, Raman spectroscopy, semiconductor industry, composition detection, color mixing and matching;
Biomedical applications, fluorescence measurements, gemstone composition detection, oxygen concentration sensors, vacuum chamber coating process monitoring, film thickness measurement, LED measurements, emission spectra Measurement, LED measurement, emission spectrum measurement, UV/visible absorption spectrum measurement, color measurement and other fields of application.
