Display Optical Measurement System - FPM H Series

FPM F Series
Large Display Optical Measurement Systems

The FPM F Series is our largest series of test systems for up to 110″ displays.

Our FPM F Series can be setup to run many standard VESA, ICDM, TCO, ISO, SPWG and other display optical 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 about the FPM capabilities.

Display Size

Test up to 110″ displays with five axis motion control and measurement spot tracking for quick and accurate measurements

Optical Instruments

Mount up to 3 instruments at a time. Software control 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

Test without moving the display

All of our FPM F Series systems include a five-axis motion system comprised of a three-axis instrument deck and a two-axis gimbaled optical probe to perform measurements while the display remains fixed and in an upright position. This design allows for viewing angle measurements without moving or rotating the large and heavy display module thus avoiding potential mechanical strains and unexpected thermal gradients within the display or TV.


Up to 84″ Displays

For large displays, our FPM-530-FO is designed to perform full optical performance tests on displays up to 84” (213 cm).


Up to 110″ Displays

For very large displays, our FPM-540-FO is designed to perform full optical performance tests on displays up to 110” (279 cm).

Full optical characterization

Our FPM F 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 direct view or fiber-coupled 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, Optronic Laboratories, and Minolta. 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 F Series can be customized to accommodate (hardware integration) up to 3 optical instruments depending on your display metrology needs. The FPM F Series comes standard with a fiber-coupled spectrometer and options for up to two additional direct-view instruments.  The FPM F 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.

Test Pattern


TestStand - Automated Test Sequencer

For automated test scripts, the FPM F 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 F 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)
  • Enhanced measurement history and reporting tools (print standard measurement reports from the MCI).
