Overview
Admesy colourimeters offer advanced optical filters which are near-perfect to the CIE 1931 colour matching function. This results in the highest possible accuracy, even for displays where the spectral power distribution may vary.
Very uniquely, Admesy manufacturer their own thin-film filters in-house, enabling accuracy beyond any alternative colourimeter manufacturer.
Admesy colourimeters are available with different lenses, with 10mm, 20mm or 27mm lens size suitable for display calibration, and for small areas of interest lens version are available with 2.1mm or 5mm sizes.

Admesy colourimeters can store up to 30 individual display matching matrices, enabling specific display technology to be matched.
Note: Internal probe matrices should not be relied on for calibration accuracy - the use of Probe Matching to a Spectro is always recommended, using ColourSpace's unique FCVM or MPVM probe matching, although the ability exists to force use of the tradition simple FCMM matrix method.
Admesy colourimeter software enables user to generate their own matrices, and upload into the probe, as well as managing other aspects of the probe configuration that are outside of the needs of ColourSpace use.
Accessories

- Tripod Mounting Attachment
- Straylight protection tube
Light Illusion can supply any additional accessory as listed on the Admesy website.
Pricing on request.

Custom 3D Printed Mount
On request 3D drawings to enable a user to print a combined Hera/PCM2 or Prometheus mount is available as an alternative to the metal tripod mounting plate. The 3D printed mount holds a Hera and Prometheus or PCM2 in the same holder/position for probe matching.
Recalibration/Re-certification
Admesy colourimeters should not require factory recalibration, as the optical filters do not age within the typical lifespan of the product.
See the Admesy Website for further information.

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 Admesy colourimeters.
Admesy Colourimeter Settings
The Settings options provide specific Admesy configurations, and will show the model series name of the connected probe.
Full details for all options can be found within Admesy's own documentation.
Note: ColourSpace does not use Flicker, Response Time, etc. modes, are they are not valid for display calibration.
Integration Time
Integration Time sets the time taken for any given single measurement, in micro-seconds.
The default setting is as shown, although different values will likely be required depending on the display being profiled, with longer values generating more accurate and stable readings.
Gain
The drop-down sets the probe sensitivity, with Low(1) being most sensitive.
(Using low gain may cause clipping with hight brightness values.)
Note: Both the above settings will be defined automatically when Auto Range is Enabled.
SWB Cal. Matrix
The drop-down menu provides access to any pre-set matrices held within the Admesy probe.
Note: Internal probe matrices or matching should not be relied on for calibration accuracy - the use of Probe Matching to a Spectro is always recommended, using ColourSpace's unique FCVM or MPVM probe matching.
Auto Range Parameters
Manually setting Integration Time and Gain values can be complex as the optimal settings depend on the luminance of the screen being measured. The Auto Range function can be used to define optimum settings during measurement, and can be fine-tuned for better stability levels by manually setting the available Auto Range Parameters.
Enable
The tick box sets Auto Range Parameters Off or On.
Note: Intelligent Integration is disabled when Auto Range is set to On.
Frequency (Hz)
The frame rate of the display being measured, in the range 1 to 255 Hz.
Manually entering the video signal frequency - 60Hz, 50Hz, etc. - is usually preferable.
Adjmin (%)
The minimum level to adjust to, based on the scale of the ADC expressed in %. The higher this level is set, the more stable the measurement, as well as being slower.
Max Int. Time (μSec)
Sets a clip point beyond which integration will cease to operate, to prevent excessively long readings.
Average
Used to define the the number of readings to average.
Intelligent Integration
Intelligent Integration sets the nits level under which Intelligent Integration will be used.
This provides the best possible low-light measurements, without impacting reading speeds at luma levels above the set value, so maintaining overall speed of profiling.
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.
Average Low Light should not need to be used when Intelligent Integration is active.
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 Spectrometer, 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).
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.
Note: Some probe/settings/display combinations will not work accurately with the Auto function
