Ambient tab
Specify the ambient light in the viewing area. Select the ambient light
description that best fits the display location:
• Low (reading room - 0.20 cd/m
2
)
• Moderate (typical office - 0.80 cd/m
2
)
• High (brightly lit office - 1.50 cd/m
2
)
• Custom – Fill in a value ranging from 0.00 (default) to 5.00 cd/m

.
The RightLight service allows you to enter luminance in cd/m
2
resulting from the diffuse reflection of ambient illuminance.
Since typical Dome panels have a reflectance of 1.25%, given
illuminance E in lux, you can calculate the luminance in cd/m
2
using this equation:
luminance = 1.25%

E /

The default values are typical of reading rooms (approx. 50 lux),
moderately bright offices (approx. 200 lux), and brightly lit offices
(approx. 375 lux).
NOTE: Choosing the Native or the No RightLight Calibration option on
the Calibration tab or on the services menu prevents RightLight from
correcting for ambient light. When you do this, you are no longer
applying DICOM calibration.
