CR-100 Probe

Colorimetry Research CR-100 Tristimulus Colourimeter

The Colorimetry Research CR-100 is completely solid-state with no mechanical shutter or moving parts to ensure high reliability and long MTBF, with high operational speed, and impressive low light measurement capability.


Overview

CR-100 Probe

The CR-100 is designed for all display types, and can measure all projection as well as all luminous display technologies, and uses the Four-Colour Matrix method, developed by the National Institute of Standards and Technology (NIST), and improves the accuracy of tristimulus colourimeters for measurements of colour displays and has been verified to be ideal for DLP, D-ILA, SXRD, cathode rays tubes (CRTs), liquid crystal displays (LCDs), plasma, and organic light emitting diodes (OLED) displays.

Each CR-100 goes through a strict quality control process, with every tristimulus filter measured using a double monochromator and the results are provided along with the relative errors at 1 nm wavelength increments, so the user can verify that his instrument is within the maximum f1' errors guaranteed. No pre use calibration (black/white) is required.
(See below for specifications)

A NIST traceable calibration certificate is included with every probe.

LightSpace CMS Compatibility

The CR-100 is one of the recommended probes for use with LightSpace CMS as it provides an ideal combination of speed, low-light reading, and accuracy, three key capabilities that combine with LightSpace CMS to provide the best possible final calibration, especially when combined with the unique large cube size profiling capability of LightSpace.

The CR-100 can store up to 20 individual display matrices, enabling specific display technology to perfectly matched.

The included CRI App from Colorimetry Research enables user to generate their own matrices, and upload into the probe those provided as standard from Colourimetry Research, or even third parties.


LightSpace CMS Integration

As with all probes, the CR-100 operation and function is controlled via the 'Options' menu, accessed via the Calibration Interface, or Display Characterisation windows.

The CR-100 has a range of variables that are directly associated with the probe - including Exposure Multiplier, Max Exposure Time, Sync Frequency, and probe Calibration Settings (Matrix pre-sets).
(This obviously ignores settings that are generic, such as Extra Delay Time, Probe Matching, Probe Offset, Luminance Units.)

CR-250 Options

The options are:

  • Exposure Multiplayer: increases the exposure time by the selected multiple, increasing sensitivity & repeatability
    For example, the CR-100 can measure 0.003 nits with 0.5 sec exposure and 0.0007 nits with 20 sec
  • Max Exposure: sets the maximum exposure time for any given reading
    The default setting is 200 ms, which sets a maximum patch read time of approximately 1.5 seconds, with an Exposure Multiplayer of 1
    (If using 'Closed Loop' mode within LightSpace (rather than DIP Mode) we would never recommend a Max Exposure value lower than 200ms. With DIP mode you need to select the highest value that gives you the desired patch read time for your specific DIP mode sequence).
Max Exposure 500 msec. 250 msec. 100 msec.
Luminance (nits) Total Read Time (seconds)
100 and above 0.12 0.12 0.12
35 0.18 0.18 0.18
7 0.56 0.56 0.56
3.5 0.8 0.8 0.8
0.35 2.0 1.5 0.94
0.035 and below 3.3 1.75 0.94
  • Sync Frequency: the Manual Sync Frequency value is set automatically when the CR-100 is first connected, by reading a bright patch on the display to be profiled. The 'Auto' setting should only be used if making manual (consistent) readings on a display where the display refresh rate changes. The 'None' setting should be used only when the light source you are measuring has a constant light output with no modulation or "refresh cycles". It should never be used when measuring/calibrating displays or projectors
    The 'Probe Calibration' button can be used at any time to re-set the Manual Sync Frequency
  • Calibration Settings: using the drop-down menu any pre-set Matrix held with the CR-100 can be selected
    The Matrix presets match the probe to different display technologies - specifically the backlight/illumination spectral response

If using the Probe Matching function (Active Probe/Display Data) to pre-profile a Tristimulus probe to a Spectro, the same 'Calibration Matrix' should be used for the Tristimulus probe as was used when the Probe Matching data was generated.

For further information on the additional setting with the 'Options' menu see the Profiling Manual page.
