basICColor DISCUS Tristimulus Colourimeter

The basICColor DISCUS Probe can deliver quality results at an efficient price point, and performs well with all display devices, from projection to LCD, from plasma to CRT, using encapsulated optics and thin-film glass filters to guarantee long term stability of measurement values. The basICColor DISCUS is ideal for today's new HDR displays, as it has a peak luma capability of up to 2500 nits.

Note: Delivery timescales for the DISCUS are presently approx. 4 weeks from order.


basICColor DISCUS Probe

Using a built-in temperature sensor the basICColor DISCUS compensates for incremental heating during profiling, ensuring reliable and constant measurement values, especially with critical dark colours.

The basICColor DISCUS is designed for measurement of any display technology found in DI environments, from monitor displays to projection systems, and provides highly-accurate results to guarantee colour calibration.

Each DISCUS is factory calibrated individually and can be re-certified as required, ensuring the Discus remains highly accurate throughout its operational life.

Note: The Discus has no 'Sync' function, and can require longer integration times on some displays types, such as PWM (pulse width modulation) displays.

LightSpace CMS Integration

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

The Discus has two main variables that are directly associated with the probe - Integration Time and Calibration Settings (Matrix pre-sets).
(This obviously ignores settings that are generic, such as Extra Delay Time, Probe Matching, Probe Offset, Luminance Units.)

Discus Options

The options are:

  • Integration Time: sets the integration time for any given reading, using 4 presets 0-3
    Setting 0 uses short measurement times, and averages 4-6 measurements
    Setting 1 uses short measurement times and averages 10 measurements
    Setting 2 uses long measurement times and averages 4-6 measurements
    Setting 3 uses long measurement times and averages 10 measurements

Setting 0 is the default, with setting 1 used for higher precision.
Settings 2 and 3 use integration times that are 4 times as long as settings 0 and 1.

Integration Time Setting-0 Setting-1 Setting-2 Setting-3
Luminance (nits) Total Read Time (seconds)
3000 0.3 0.4 0.5 0.5
1500 0.4 0.5 0.5 0.7
750 0.6 0.9 0.7 1.0
375 1.0 1.5 1.0 1.5
188 0.4 0.5 1.8 2.8
94 0.5 0.8 2.3 5.3
47 0.9 1.4 1.1 1.6
23 1.7 2.7 1.9 2.9
12 2.2 5.3 2.4 5.5
6 4.3 10.4 4.5 10.6
  • Calibration Settings: using the drop-down menu any pre-set Matrix held with the Discus 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 'preset matrix' should always be used for the Tristimulus probe as was used when the Probe Matching data was generated.

For further information on the additional settings within the 'Options' menu see the Profiling Manual page.
