MK550T Handheld Spectroradiometer

Cost effective, practical analytics for Display Panel Manufacturers

Lab and research equipment can be impractical for many companies needing to evaluate Display Panels in different situations.   The MK550T spectroradiometer is cost effective, lab-level and versatile – just right for production-line QC, R&D testing, or Field Application Engineering work.

MK550T Handheld Spectroradiometer


Companies that manufacture, buy and sell display panels face a similar problem and that is the need for efficiently measuring Display Panel performance in various situations, like on production lines, R&D test labs, FAE offsite locations.

The choices are few. Use a simple Colorimeter that is portable but inaccurate or you can use laboratory-level equipment, which is accurate but slow, bulky and expensive.

With the MK550T handheld spectroradiometer, anyone has access to cost-effective, lab-level instrumentation that can measure up to 10x faster than other precision instrumentation. 

The MK550T is used in manufacturing R&D development. It is used on production lines interfacing with manufacturing production equipment.  It is used by Field Application Engineers for remote site OEM/ODM work.

MK550T – Boost versatility & flexibility in measurement capabilities through portable, fast performance.

    • Laboratory-Level precision – Diffraction Grating and proprietary technologies
    • Different receptor sizes (for small size displays – e.g. watches)
    • SDK allows manufacturers to integrate with their own RD efforts
    • Supports XYZ Matrix Calibration, Calman Studios
    • JEITA, Contrast, VESA, RMS, FFT Flicker metrics
    • Handheld versatility and can also mount on a stand, cable connect to PC for hands free operations.

LabResearch level precision – Diffraction Grating

A 3-color sensor RGB colorimeter can perform  tasks to evaluate Display Panels but with significant room for error. Most Display Manufacturers find this unacceptable.

The MK550T uses a Diffraction Grating technology which can slice up a color spectrum into 1nm increments (up to 400 wavelength colors).  Infused with a 10-year development effort in proprietary technologies, UPRtek delivers lab-level measurement accuracy that is being actively used in production lines of various Display Panel manufacturers.

Innaccuracies using 3-color RGB Colorimeter

MK550T has several receptor size options

(Ø10mm, Ø5mm, Ø4mm, Ø3mm)

The MK550T comes in several receptor size models for large displays (display panels) and small displays (e.g. watches, cell phones).

Ensuring measurement accuracy

Measurement devices also have to abide by globally accepted standards.  This also helps to ensure optimal accuracy, accepted by the industry community. 

The MKT550 is supported by Calman Studios allowing R&D to efficiently test and calibrate panels during development.

Additionally, MK550T provides SDK facilities to integrate with companies using their own RD software/hardware support.

Evaluating Flicker

MK550T can evaluate flicker for Display Panels or use traditional Light flicker metrics

Display Panel Flicker: SVM, JEITA, VESA, RMS

Light flicker metrics: Flicker Index, Flicker Percentage

Connect-up for Big View & Data Analytics

One of our most popular features.  The MK550T can connect to mobile and PC devices through USB cable, for full screen viewing, data collection and export to popular software.
