Are there any LED light sources that can adjust the wavelength?
The LED spectrum is narrow, the common red LED wavelength is about 650nm, the infrared LED wavelength is about 940nm, the general single LED product spectrum range is 40~50nm. It is difficult to implement continuous optical LED from 600nm to 2500nm. At present, the existing products can not be achieved, there is no hope in the short term.
600nm to the 2500nm light source is red and infrared, can achieve the xenon lamp and halogen lamp, xenon lamp and better, the two lamp can produce a wide spectrum of light, through the filter, filter out the following 600nm, 2500nm and the light of the above, you can get 600nm to 2500nm light.
If you want to control the change of wavelength, the feasible method is single xenon lamp + mechanical transform filter. Or circuit controlled multiple light sources. Personal views, for reference.
