LED Test Instrument to analyze LED performance / Determination of color of LED light / 
Measurement of Color temperature / Lux measurement / Spectral analysis on lighting 


The LED spectrometer MK350S is applied to measure LEDs. The LED spectrometer performs a spectral analysis on light, which is emitted by LEDs. The MK350S LED spectrometer measures besides the color spectrum also the illumination level in Lux, the color temperature and many other parameters, that are used for the selection of LEDs. This professionally used LED spectrometer features a touch screen for an easier navigation.

The menu navigation is self explanatory, so even beginners can easily operate the LED spectrometer. The results of the LED spectrometer are saved on a SD memory card. This SD memory card not only stores the data, but also facilitates as a WiFi interface. Thus the LED spectrometer can be connected with an Apple or Android device. After downloading the relevant app, the device can be used for remote controlling the LED spectrometer ML350S. Addionally, uSpectrum PC software can be downloaded to review the data.

The cosine correction is a necessary application for the measurement of color and quality of various light sources. The reflection of light that hits an objects depends on that impact angle. The more acute the impact angle, the more the reflection. So if the light does not hit the object in a rectangular angle, the spectrometer would otherwise measure much to low values. But by using the cosine correction the values are much more accurate.
