Laser Button
The laser pointer is used to illuminate and identify features in the image. The
laser pointer illuminates the area of the scene that coincides with the green
circle indicator on the display – see Figure 9.
NOTE
: The laser is aligned to illuminate objects at a distance of 9.84 feet (3m)
from the front of the imager

3.4.9.1 Brightness & Contrast Definitions
The thermal brightness is the color at the center of the color scale, (the default thermal brightness for the rainbow color
palette is a yellow/green color see Figure 18). Note that the brightness of the image does not refer to the brightness of the
screen. For a grayscale image, brighter means whiter, and for a rainbow image, yellow is brighter than blue, and red is
brighter than yellow. The contrast is the amount of the color bar that the image uses, and it uses the whole color bar by
default.
Figure 18: Brightness & Contrast Definitions
The target thermal brightness and contrast of the auto mode can be manually set when B – C is toggled to “ON” in the
camera settings menu. This enables hot button 3 to be toggled to B-C when the imager is in auto mode. In this case the
“right” and “left” buttons will increase and decrease the contrast of the image. The “up” and “down” buttons will increase
and decrease the thermal brightness of the image.
Brightness = (Center of color bar) = Yellow/Green by default
Contrast = (Amount of color bar) = Entire color bar by default
