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

)

• Moderate (typical office - 0.80 cd/m

)

• High (brightly lit office - 1.50 cd/m

)

• 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

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

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.
