Optical Performance Measurement Redefined

Reflective Display Measurement System

The FPM-505R is designed for reflective measurements and other standard optical performance tests of reflective, transflective, emissive, and transmissive displays.

If you need to test sunlight readability, measure thermal performance, or automate optical tests for automotive, avionic, or mobile displays, the 505R can handle it all.

Test Pattern

Automated test pattern generation

Of course, automated display testing doesn’t stop with the instrument and a positioning system. You need to automate display drive using a lcd tester or test pattern generator that can drive display modules or finished products.

Our most popular lcd tester for display drive is our T-Drive III but as with optical instruments, our ViewPoint software can interface with most test pattern generators on the market today. We even offer custom software interfaces to work with specialty LCD drive equipment.

If you need a test pattern generator as part of your optical measurement system, check out our LCD Testers or Contact Us to find out which lcd tester will work with your displays.

Optical Measurement Report - Westar

Customizable reports

The FPM-505R comes standard with Microsoft Excel for data reporting.  Use one of our pre-formatted reports or design your own.


TestStand - Automated Test Sequencer

For automated test scripts, the FPM-505R can be controlled using NI TestStand. Any controls in ViewPoint are available via test objects (steps) in TestStand making it easy to build elaborate test sequences. Westar offers many standard test sequences and can help you design your own custom test sequences depending on your display metrology needs.
NI TestStand Automated Test Software


  • Access motion base, instruments, test pattern generators, and other supported devices using test objects
  • Structure test steps into sequences and subsequences with global and local parameters
  • Powerful development interface for sequence design and debugging
  • Easy to user interface for sequence operation and control.
  • Access Microsoft Excel for data reporting

ViewPoint - Manual Control Interface

The FPM-505R comes with a sleek user interface for manual control called ViewPoint. In a single interface, the user can control the instruments, light sources, test pattern generators, and motion base. ViewPoint can be customized with software controls for your specific instruments, test pattern generators, and power supplies.

ViewPoint Manual Control Interface


  • Access motion base, instruments, test pattern generators, and other supported devices
  • Multi-view dockable GUI windows – arrange multiple DUT Control, Motion Control, and LMD GUIs
  • Property grids for easy parameter input
  • Enhanced CIE chromaticity charts (NTSC reference gamut, multiple measurement points, print graphs)
  • Enhanced measurement history and reporting tools (print standard measurement reports from the MCI).
