There are difference adapters “Aperture” available to adapt for the sensor in the package the angle of incidence and/or to fix the sensor system.
The JCDK-Aperture-135 is designed to limit the angle of incidence on the AS73210 to ±10°. It is an optional aperture of the JCDK assortment and characterized with a single groove outside. The outside diameter of
25mm makes it compatible with JCDK-1/4”-Adapter and opto-mechanical system parts (e.g. Linos). In front of the aperture is space for mounting a filter glass with outside diameter up to 22.2 mm and thickness up to mm.
JCDK-1/4“-Adapter is used for mounting the JENCOLOR ® DKs on a camera tripod or equivalent holders. On the bottom side there is a centered 1/4”-20 UNC internal thread and 20mm below the optical axis there are two M4 internal threads for mounting the JCDK-1/4“-Adapter on a flat surface. For IR sensible applications order the JCDK aperture 13.5 with inserted IR blocking. For using the adapter with an alternative integrated filter please ask our sales team.
Via the JCDK-SMA-Adapter a fiber optic patch cable with F-SMA 905 plug can be connected to the
JENCOLOR ® Development Kit. The distance between fiber end and sensor is calculated to achieve an angle of incidence of at most 10° with a fiber core diameter up to 600µm. Minimum NA for illumination of the whole sensor area is 0.22 and to reduce the effect of stray light inside the adapter and the case NA should not exceed 0.39.

5.5 Basics for Measurements
Each ADC value (Analog-Digital Converted value) is calculated to a photocurrent (“photocurrent_nA”) under consideration of dark current (“zero”), reference current (“refCurrent_nA”) and integration time (“nClck”).
These steps are performed before this value is used for any calibration or colorimetric functions. The following virtual code is used for each sensor channel value - whereas the ADC is the 16bit read out value:
% Correction ofbit shift (register CREGH)
% divider = 1 (off), 2, 4, 8 or 16
Adc = Adc * divider;
% Calcualtion of the maximum number of clocks nClck
% intTime_ms is the integration time in milliseconds (register CREGL) bit = 10 + log2(intTime_ms); nClck = 2^bit;
% Check of saturation sat = nClck - 1; if sat > 65535
sat = 65535; end if Adc >= sat
% Error! Sensor channel is saturated! ams.com db13386e_V2.01_certified_2017-07-06 Page 16 of 30
AS73210-AS89010-AB4 SET DK
V2.01
else
% Measurement is ok. end
% Correction of zero offset (register OPTREG)
% zero = 0 (disabled), 15, 31 or 63
Adc = Adc - zero;
% Calculation of photo current in nano ampere photocurrent_nA = Adc * refCurrent_nA / nClck;
A detailed description of the sensor signal calculation is included in the datasheets of JENCOLOR ® key components, white papers or application notes. Please ask our sales team for further information.
To perform absolute color measurements or for further evaluation of the results in any color space, the sensors system DK AS73210-AS89010-AB4 must be calibrated to the specific application or test setup.
Please ensure that all continuous processes, measurements and the calibration procedures are performed based on same conditions. These aspects refer to the DUT (device under test), distances between DUT and sensor as well as all initialization and environment conditions. The sensor, selected illumination and target are used in a closed system for calibration and measurement procedures. A new calibration is required if you change any conditions inside this closed system.
5.6 Calibration
The calibration option is used to create an application and sensor specific calibration via calibration targets measured by a reference device like a spectrometer. The standard calibration simply uses an identity matrix which approximates the color space values. Therefore it is recommended to calibrate the sensor/application to get accurate results and coordinates in any color spaces. This section describes how to calibrate the device.
First set the observer with which the reference values are measured (see colorimetric settings of your reference device alike a spectrometer or others).
Figure 18: Calibration - Observer
Then choose whether the calibration matrix should be inserted manually or to measure it.
Figure 19: Calibration - Targets measure or manually - ams.com db13386e_V2.01_certified_2017-07-06 Page 17 of 30
AS73210-AS89010-AB4 SET DK
V2.01
After choosing Import the calibration matrix and offset values must be inserted e.g. from an Excel sheet like shown in the following figure. Just select the cells for import and press the button Import from xls.
Figure 20: Calibration - Manual, insert matrix
In the next step the offset values for the sensor must be imported.
Figure 21: Calibration - ADC offset values
After choosing the Measure option, it is required to enter the amount of calibration targets those want to be measured. The minimal amount of targets is the number of sensor channels. The DK AS73210-AS89010-
AB4 uses at least 3 channels.
Next, the software requests to cover the sensor for an offset measurement. After this following the software performs measurements for each target and guides the user through the process step by step.
Figure 22: Calibration - Measurement steps Dark measurement and measurements of targets -
In the final step, the software requests to insert XYZ values measured from the reference device. It is possible to save the results of the calibration process into a special owner configuration file.
If any support during the sensor calibration is needed, please contact our sales team. ams.com db13386e_V2.01_certified_2017-07-06 Page 18 of 30

Figure 23: Calibration - Input XYZ reference values -
A calibration is valid for the used system and must not be re-calibrated until not relevant system configurations or parameters for measurement were changed (e.g. integration time). After changing the configuration file the software always tests the specified parameters if a re-calibration is necessary and shows the message "No calibration loaded” or “Calibrated with different settings”. In this case the calibration must be performed again to achieve exact results. Please note, the software only tests known parameters of the test software and cannot check if any external conditions in the test system were changed. Ask our sales team for support during the calibration process or if you will not get the specified results after calibration.
5.7 Load/Save menu
The Load and Save menus provide the option to load and save the configuration, calibration and measurement values in a file with the extension *.dat (‘Load config and measure data’; ‘Save config and measure data’). To simply load a configuration of the sensor use the Load config menu entry. This allows
you to load a *.csv (*.csv – comma separated values) configuration file (see chapter 5.8).
The Save menu also offers an extra feature to export measurement values to *.csv files or the actual sensor configuration and measurement values to an Excel file (*.xls) for further usage. This data can be used for comparison or for statistical calculations. Note: The export to Excel is only available if Excel is properly installed on your local PC.
Figure 24: Menu - Load and Save
5.8 Configuration Files (*.csv)
The Configuration Files (*.csv – comma separated values) contain all important information about the measurement and configuration behavior. The files are used for application-specific adjustment of the test board AS73210-AS89010-AB4 and/or compatible boards. In the installation path of the test software you find several examples for a configuration file like “command example.csv” or “command example AS89010-
EB1.csv” 7 . Processing these *.csv-files is possible with a text editor, Open Office Software or MS Excel.
Please note, however compliance with the syntax and the extension *.csv when saving. Other-wise, errors

All grey highlighted columns are comments or user information with no conditions for syntax except for the use of the separation of characters like “,” or “;”. In case of using JENCOLOR ® sensors a changing of the line with the keyword “ChannelOrder” is not necessary because the filter set was pre-defined. On the other side by using alternative sensor boards the ChannelOrder must be adapted based on the any special configuration. Check the installation or support files like readme.txt or datasheet for more details.
To use a configuration file, select the file and load it by mouse click. Then the parameters inside the files specified will be used. ams.com db13386e_V2.01_certified_2017-07-06 Page 20 of 30

All commands and data refer to the I²C communication and register settings of the Sensor signal ASIC AS89010. For more details please check the description in the datasheet of the AS89010 [1].
Description of *.csv columns:
“State” All rows containing “Init” are send to the AS73210-AS89010-AB4 to initialize the AS89010 after choosing a configuration .
Important: Do only use the commands “ChannelOrder”, “Init” and “Measure” (case sensitive)! Do not mix “Init” and “Measure” rows!
“Info Register”,
“Info Data”, Columns are not relevant for a functional use.
“Comment”
“Read/Write” Insert “W” for write I 2 C data or “R” for read I 2 C data.
“I 2 C Address” Insert “E8” for write and “E9” for read I 2 C data.
“Register” For write I 2 C: Insert the register address which should be written to. Important: Only insert decimal values 0...255!
For read I 2 C: Leave it empty.
“Data” For write I 2 C: Insert the data which should be written. Important: Only insert decimal values 0...255!
For read I
2
C: Insert the amount of bytes which should be read.
Attention:
The JENCOLOR ® AS73210-AS89010-AB4 Evaluation Software is designed like as a simple terminal program. This means that each write and read command
(each row of configuration file) is written or read via I 2 C without checking the validation of data. For detailed description of all registers check the datasheet of
AS89010 [1]. The JENCOLOR ® AS73210-AS89010-AB4 Evaluation Software can only be used in Command and Continuous mode (compare register CREGH of
AS89010).
After software installation in the software directory “application” some samples of *.csv files show several examples to set the system, write/read registers and measure in different modes. ams.com db13386e_V2.01_certified_2017-07-06 Page 23 of 30

In/Decrease until the digits are in a range with an excellent ratio between noise (digits) and brightness digits
(several thousands, max. without saturation, in case of saturation consider also divider)
An ideal ratio between noise (digits) and brightness digits needs to be found (several thousands)
To prevent the risk of saturation increase divider as long as the sensor is not in saturation otherwise decrease gain or

7 EXAMPLE FOR MEASUREMENT
The AS73210-AS89010-AB4 test system is ideal to detect and measure colors, color temperatures or brightness of lighting signals 8 . Typical applications are LED control and measurement and/or calibration of video walls and monitors.
Please note, the results was achieved by a standard and application specific calibrated test system (by using spectrometer and sensor, measured one by one, nearly at the same position). Measurements and calibration were done with a standard display under laboratory conditions. The following tables show the calculation of the calibration matrix and the results of the spectrometer, sensor and evaluation by using the set iref = 20nA, Tint = 1024ms and a RGB calibration.

8 Note, the accuracy is depend on the system conditions, calibration and interferences. Therefore in application specific systems the sensor system must be optimized to increase accuracy. E.g. IR lighting will reduce the signal noise ratio dramatically. An add-on IR g will correct that. ams.com db13386e_V2.01_certified_2017-07-06 Page 25 of 30
