Display Optical Measurement System - FPM H Series

FPM V Series
Enclosed Display Optical Measurement Systems

The FPM V Series is one of our most flexible optical performance measurement solutions that is scalable to your display measurement needs. Whether you need to test cell phone display modules for engineering development purposes, ruggedized displays for aerospace and military applications, or TV LCD modules for production QA/QC, we have a FPM solution for you.

While one of the major benefits to the FPM V Series is flexibility in interfacing with instruments, test pattern generators, etc, the FPM really shines when it comes to its testing capabilities. Our FPM V Series can be setup to run many standard VESA, ICDM, TCO, ISO, SPWG and other display measurement tests as well as many customized tests.

The baseline FPM V Series includes a three axis or five axis motion system housed in a light safe enclosure and a controller computer with software interface (manual and automated control).

Display Size

Mount up to 37″ displays with three or five axis motion control and measurement spot tracking for quick and accurate measurements

Optical Instruments

Mount up to 3 instruments at a time in a light safe enclosed system. Software integration for most of the popular optical instruments available


Automated Tests

Automate many of the standard VESA, ICDM, TCO, ISO, SAE, MIL-L and SPWG tests. Supports a wide variety of standard and custom optical performance tests

Test Pattern Generators

Automated control of the Westar T-Drive LCD Tester and many other popular test pattern generators on the market today

Automated 5-Axis or 3-Axis motion base for up to 37″ displays

Display Optical Measurement System - FPM H Series


The FPM V Series includes a three-axis or five-axis motion system and a controller computer with software interface (manual and automated control). We offer two standard models based on your display testing requirements, the FPM-505W or the FPM-305W.


5-Axis System with Goniometer

The FPM-505W includes a polar Goniometer for viewing angle performance measurements of displays up to 27″.  This makes it ideal for small to mid-sized displays and devices such as cell phone, tablet, and notebook displays requiring full optical characterization.

3-Axis System

The FPM-305W is a three-axis system for optical performance measurements of displays up to 37″.  It can be used when viewing angle tests aren’t necessary or with instruments capable of performing viewing angle measurements.  Like the FPM-505W, the FPM-305W is ideal for small to mid-sized displays.

Full optical characterization

Our FPM V Series can be set up to run many standard VESA, ICDM, SAE, TCO, ISO, SPWG and other display measurement tests as well as programmable customized tests. We offer test sequences that cover most display measurement requirements or you can write your own. Contact Us to learn more.

Note: Test capabilities vary based on system configuration and are dependent on options such as the optical instrument, test pattern generator, and baseline system.

Wide selection of optical instruments supported

Works with optical instruments from all the popular brands

Our Display Measurement Systems work with more LMDs than any other display measurement system. Our systems support standard photometers and spectroradiometers from Topcon, Photo Research, Minolta, Radiant, Gamma Scientific, Optronic Laboratories, and BW-Tek. This broad range of available instrument interfaces allows you to pick the best instrument for the job

Install and control up to 3 instruments

The FPM V Series can be customized to accommodate (hardware integration) up to 3 optical instruments depending on your display metrology needs.  If you already have an instrument, we most likely can support it with our system software and hardware.  If you don’t have an instrument, we can help you select the right one. The FPM V Series supports the following instruments:

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

Our FPM V Series 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 V Series 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 V Series 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)
