The displayed value of 26.3 is the reflectance that corresponds to either Rmin or
Rmax reflectance. The X and Y numbers are the pixel positions in the image. The
value D is the configured diameter of the simulated light point. Typical measurement
apertures (also where simulated light point diameter = synthetic aperture) range from
100 µm (4 mil) to 500 µm (20 mil). Values exceed or fall short of this range in
exceptional cases only.

Configuring measurement image size
The measurement image can be shown at high levels of magnification or reduction.
The buttons
are used to alter the display. The percentage value indicates the magnification. The
value 45.8 µm/pixel depends on the focal length of the lens used and is determined
by the adjustment process.
If the mouse pointer is located in the image, the image can be magnified or reduced
by scrolling the mouse wheel. It can be magnified to an extent where the camera
chip's individual pixels are visible and distinguishable.
7.12
Rotating the image
The position of the REA MLV-2D may mean that the image does not move as would be
intuitively expected. For this reason, the green arrow symbols can be used to
rotate the image until the movement coincides with what we would expect intuitively.
