Leading Sustainable Product Innovation

Portable Light Spectrometer (spectrophotometer)

We are happy to launch a revolutionary new products - Portable all-in-one spectrometers (spectrophotometer) for testing lighting quality of the ambient environment and all lighting products, especially LED light sources.

UPRTEK AI-MK350 Spectrometer (spectrophotometer) family are the first lightweight, handheld, portable LED light spectrometer with a color screen which does not require a computer.  They include MK350(first generation product, replaced by MK350N Plus), MK350N Plus, advanced version MK350S, portable version MK350D and economic MF250 flicker meter,  Click here for comparison. This portable spectrometer can be used for LED / OLED lighting research and development, quality control of all lighting products, horticulture lighting management, as well as conventional architectural and stage/studio lighting studies.

With one click, in addition to viewing the full-color spectrum in color, you can also get the following lighting data: CCT, CRI, LUX, Lambda Peak, CIE1931, CIE 1976.  All of this in the palm of your hand, no computer need.   

2018 new version MK350S premium , MK350N Premium 

2018 new version, MK350N Premium, replace MK350N Plus, Spectrometer		MF250, Affordable flicker meter, latest!	MK350D, portable and compact	MK350S, Advanced  (more info)

You can analyze spectrum of LED lights on site with no additional equipment, this is the fastest and most economic lighting analyzing tool so far, this device is good for LED/OLED research and development, lighting designer, interior designer, plant research /LED grow lights application, outdoor ads display screen, auto lights, food store illuminating, art and museum lights et al.  

 Accuracy and Reliability

Accuracy and reliability of spectrometer is main consideration except portable benefit, we tested a few single wavelength LEDs and multiple wavelengths fixtures from different manufacturers, below are results. In summary, AI-MK350 spectrum data is very close to data tested by standard spectrometer or data provided by manufacturers, therefore, this handheld spectrometer will be used to wide field with its portability, accuracy, simplicity  and affordable price.

Note：Test condition is not controlled by professional darkroom, the result may be interfered by other lighting source, e.g office lights, sunshine et al.
