The Technology: Diffraction Grating

Simple colorimeters can only capture a spectrum with 3-color RGB filter and color sensor. The MK350N Premium uses a diffraction grating that is more accurate and discerning when distinguishing colors. Accuracy is paramount when measuring light to meet global measurement standards.

Popular Feature – What you see is what you can store 

Numbers, graphics, comparisons you see on the screen can all be stored. This has proven to be one of our most convenient features. It is the ability to collect all the data you see, screen by screen, for easy recall, evaluation and analysis, back at the office.

Essential Gear: Flicker and Blue Light Hazard

The deleterious effects of Flicker and Blue Light Hazard are well documented, and subject to scrutiny by standards and government organizations. The MK350N Premium comes with features to evaluate and assess both.

Seamless – Connect, Transport and Export

Our most downloaded files are our uSpectrum Apps and PC software that allows connectivity between the MK350N Premium to the greater digital world (PCs, mobile devices).  Handheld spectrometers are built to be compact and portable.  But when you need a keyboard and full-screen, it’s work-saving, time-saving and eye-opening.

uSpectrum PC Spectrum Software also allows data to be seamlessly transported over USB cable.  The information is data-ready for import by popular software (e.g. Excel).
