The basICColor DISCUS can deliver quality results at an efficient price point, and performs well with all display devices.

The basICColor DISCUS uses encapsulated optics and thin-film glass filters to guarantee long term stability of measurement values, and has a peak luma capability of up to 2500 nits.

ColourSpace Integration

As with all probes, operation and function is controlled via the Probe Options menu, accessed via the Profiling window, with the left-hand side of the menu providing generic probes settings, and the right-hand side settings specific to the DISCUS.


Integration Time

Integration Time sets the integration time for any given reading, using 4 presets 0-3.

  • Normal Precision - uses short measurement times, and averages 4-6 measurements
  • High Averaging - uses short measurement times and averages 10 measurements
  • Long Integration - uses long measurement times and averages 4-6 measurements
  • High Averaging & Long Integration - uses long measurement times and averages 10 measurements

Normal Precision is the default, with setting High Averaging used for higher precision.
Long Integration and high Averaging & Long Integration use integration times that are 4 times as long.


Calibration Settings provides generic probe settings and preset Matrix options, as well as the Probe Calibration option.

Matrix Presets

The Drop-down menu provides access to the pre-set matrices held within the DISCUS.
The Matrix presets match the probe to different display technologies - specifically the backlight/illumination spectral response.
For highest accuracy ColourSpace's in-built Probe Matching should be used, as it is superior to the standard matrix matching used within any probe.

Average Low Light

Average Low Light is a probe generic option, that averages multiple readings in low-light situations using an advanced algorithm built into ColourSpace. The algorithm varies based on the probe in use to provide the best possible results.

Enable Visible Feedback

Enable Visible Feedback enables the inbuilt laser pointer, assisting with probe alignment when profiling screens from a distance.

Probe Calibration

The Probe Calibration button will save a dark current calibration reading, used to improve reading accuracy in low-lights.
Make sure the cover is rotated to cover the probe sensor.

Probe Adjustments

Probe Adjustments are generic probes settings, with consistent operation regardless of the probe in use.

Configure Matching

Probe Matching is used to match a Tristimulus to a Spectroradiometer, increasing the profile accuracy.

There are three different methods available for probe matching - ColourSpace's unique 4 Colour Volumetric Matching (FCVM), and Multi-point Volumetric Matching (MPVM), with the option to force the use of the traditional simple matrix method (FCMM).


Probe Offset enables a user to manually enter offset values for different probes/display combinations.
Perceptual Colour Match is a preferable approach.

Extra Delay

Extra Delay sets a delay time after the patch has changed before probe measurement starts, and can be set automatically via the Auto button, and manages signal path delays in the image pipeline.
When using the Auto option, Average Low Light and Intelligent Integration should not be enabled.
