- Page 3 1 Introduction 1.1 Hyperion The Hyperion series colorimeter offers a unique combination of high speed and accurate colour measurement capabilities packed in a robust package. The improvement compared to the previous colorimeters is that the Hyperion has a significant improvement on filter characteristics and an incredible speed upgrade.

- Page 5 2 Interfaces 2.1 USB interface The USB-B connector is used to connect the Hyperion to a PC/Laptop. The Hyperion uses the USBTMC class protocol and can therefore be used directly with third party provided VISA compliant libraries like NI-VISA. Hyperion can be used USB powered in case the host provides enough current.

2.3 Trigger in/out 2.4 Power connections The Hyperion colorimeter has two trigger connections. One trigger output The Hyperion should be connected to USB with enough supply or using a and one trigger input. The type of connectors is SMA. When triggering is 9V DC power supply to the RS232 connector. -

These can be programmed by the end user so that the device starts with the same settings each time it is connected. :sens:aver 1 Set averaging to 1 sample Although it's possible to program all Hyperion devices in production... -
Page 17: Auto-Ranging
7 Auto-ranging 7.1 Introduction 7.2 How auto-ranging works The Hyperion includes an auto range function. This function is useful in The auto-ranging works, by first setting a default integration time. If this case the measured object shows an unknown luminance value. In this already meets the criteria for a good measurement, the measurement will case, the Hyperion will try to find the optimum setting which is a trade-off be done using that integration time. -

Adjmin is set from 1-100, which means 1-100% of Max int = 200000 the Adjmax level (Adjmax is fixed by Admesy). These settings will provide a stable measurement on white and black.

Page 20: Hyperion Formulas
8 Hyperion formulas 8.3 XYZ to CIE 1976 UCS Yu’v’ 8.1 Formulas The Hyperion colorimeter uses an XYZ sensor, meaning that other colour u'v' is noted without the hyphen in the Hyperion commands. All Yuv spaces are being converted from XYZ. The following sections show the commands perform CIE Yu'v' calculations. -

The Hyperion has six types of flicker measurement, each with... - Page 22 After calculating the FFT, a weighting factor is applied to compensate for The amplitudes found in the previous page (P0 and P1) are reduced by human eye sensitivity to frequency. This has been defined as shown in the the factors and the final result will then be: graph and table below.
