Light is an electromagnetic wave.Its visible light wavelength is 380nm-780nm with special wavelength.Less than 380nm is ultraviolet rays,more than 780nm is infrared.Human eye can get reaction of" bright" and" color" on 380nm-780nm wavelength.So it has a special significance for the measurement of this wavelength.
CMS-3500S (350-800NM) accurate array spectroradiometer adopts the international most advanced holographic concave grating spectral technique.Its optical path design is unique with extremely low stray light. Meanwhile, we adopt Japan HAMAMATSU high accuracy TE Cooling,DLP&Plane array CCD.The test accuracy and repeatability are completely consistent with foreign similar products,with more perfect functions and all kinds of latest lighting standards

Test report
The wavelength required for plant photosynthesis is 400 ~ 720nm
400 ~520nm is easily absorbed by plant chlorophyll and carotenoids
350 ~ 520nm is conducive to the growth of foliage flowers or leafy vegetables
610 ~ 800nm is conducive to plant flowering, fruit bearing and rhizome growt
