Topcon Spectro

Topcon SR Series Spectros are portable spectroradiometer, with different specifications depending on the specific model.

  • ColourSpace INF/XPT/PRO & HTX/HTP
  • SR series spectroradiometers
  • From 0.0001 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 Topcon spectro.

Topcon Settings

The Settings options provide specific Topcon configurations. Full details for all options can be found within Topcon's own documentation.

Baud Rate

The Baud Rate sets the serial communication speed.
Communication is 8-bit, no parity, 1 stop bit, delimiter CF+LF, CS-900A Type.
(Note: The connection should be Serial, not USB.)

Metric

The Metric option sets the data the Topcon provides to ColourSpace, with the default being Yxy Only, which is much faster than Yxy + Spectral. Spectral data is for future development within ColourSpace.

Measurement Mode

Measurement Mode can be set to AUTO, FREQ, MANUAL, SYNC.
AUTO is the default, but may cause measurement errors if the display is unstable. Refer to the Topcon manual for further details on the different options.

Frequency (Hz)

Frequency is enabled when FREQ is set for Measurement Mode, and sets the expected display frequency, either refresh or frame rate.

Integration Time (mSec)

Integration time is enabled when MANUAL is set for Measurement Mode, and sets a defined time duration value.

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.

Probe Adjustments

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

Configure Matching

Probe Matching is really unnecessary with the Topcon, as it is a Spectroradiometer.
The options is provided on a Why Not basis...

Offset

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 should not be enabled.
