MD100N Desktop Spectroradiometer
Cost effective display panel evaluation on production lines
Laboratory-level spectral instrumentation is not feasible to use in production facilities – they are expensive, bulky and slow to measure. The MD100N Spectroradiometer addresses those issues with cost-effective, adaptable, flexible design with a high focus on accuracy/precision.

Introduction
Display Panel manufacturers know that it’s troublesome to maintain image quality consistency in their panels, from product to product, batch to batch.
Additionally, there has been an influx of new display technologies (LED, OLED, BLU, MiniLED, MicroLED) and applications (Micro display, AR/VR). And with them, come new challenges in light performance, quality and safety (Lv, color accuracy, contrast, gamma, metamerism, visual eye safety etc).
These manufacturers certainly have laboratory-level light measurement instrumentation to address these inconsistencies, but they are often cost-prohibitive, bulky and painfully time-consuming to be used on production lines.
The MD100N is a spectroradiometer that is cost-effective, with fast measurement times, and a focus on Laboratory-level precision. It can be used by manufacturers, OEM/ODM companies of any size and allows much more flexibility and versatility for inline product inspection.
MD100N is used with laptop/PC running the uSpectrum or uFlicker software.
MD100N Desktop Spectroradiometer
- Diffraction grating technology
- Full Flicker metrics (JEITA, CONTRAST, VESA, RMS, FFT)
- SDK interface allow own RD efforts to integrate with MD100N data.
- MD100N must be used with accompanying PC/Laptop. USB or RS232 cable connection.
- Different receptor sizes for smaller displays (e.g. watches).
- Supported by several 3rd party tuning tools
Production Line Accuracy and Speed
It’s possible to use a 3-color RGB colorimeter to evaluate panels. Of course, there is a lot of room for error and inaccuracy.
UPRtek spectroradiometers use a diffraction grating that is more accurate and discerning when distinguishing colors.
The measurement time is 10x faster than other laboratory-level instrumention, meeting most production line test speed requirements. It’s almost as fast as a Colorimeter.

Crushing Flicker and Blue Light
More than ever before, attention is being given to visual eye safety as consumers are spending more time watching TVs, monitors and cell phone displays.
Flicker is a significant problem in display panels. UPRtek provides metrics for the most commonly used standards to check for flicker.
JEITA , VESA, CONTRAST, RMS, FFT
The MD100N and MK550T are both able to meet measurement requirements for TUV Rheinland Eyesafe® safety standards. These specifications require only spectroradiometer class instrumentation to validate display panel performance for low-flicker and low-level blue light.
The need for consistency & accuracy
Offers Various Calibration Tools
UPRtek spectroradiometers are supported by calibration and tuning tools including CalMan Studio, UPRtek XYZ Matrix Calibration software, Wavelength Shift Calibration Tool and Spectral Intensity Calibration Tool.
SDK (Software Development Kit) support
The MD100N also offers SDK interface support to integrate with RD software testing efforts implemented by manufacturers.
MD100N and MK550T supported by Calman Studios
Display panels – all types and sizes
The proliferation and evolution of display panels (LED, OLED, HDR, wider gamut displays, mobile devices, wearable devices, AR/VR) has made it even more important to use convenient, versatile measuring instruments.
MD100N has different receptor sizes to adapt to most screen sizes. The smaller pinhole sizes are used to test watches and cell phone panels, especially in the compacted corner regions of the screen.
Different lens sizes allow manufacturers to test different screens size.
Full Screen View & Data Analytics
The MD100N is used with uSpectrum and uFlicker software, both of which are easily downloaded to a laptop/PC (free of charge). They allow you to Operate the MD100N easily and display configurable data sets as you prefer.
QA of Display Panels doesn’t have to be bulky, slow and expensive.
MD100N is a new spectroradiometer used to help Display Panel Manufacturers produce repeatable, color-precise products with less effort, less time, less cost, more confidence.

What is a Spectrometer, Spectrophotometer, Spectroradiometer?
In the realm of spectral devices, three devices stand out: a Spectrometer, a Spectrophotometer, and a Spectroradiometer.
However, these terms have been so interchangeably used, we understand why it might be confusing. Therefore, we felt obligated to clarify their differences in one short article. Differentiate these terms like a pro!
