General
Iris controls the contrast and focus depth of the image, and will also have an impact of the output light.
Decreasing the iris opening will increase contrast and image depth, at the same time as it decreases the
output light.
The FL40 / FS40 projectors has two irises; One in the lens, and one in the illumination path. They have both
mainly the same function, but with a small difference.
Lens iris
Located in the lens, and will increase the contrast and depth of the focus area when used. Will also have an
effect of the output light
Illumination iris
Located in the illumination path, and has less, but still an effect on the contrast and the depth of the focus
area, but will to a greater extent have an effect on the amount of output light.
How to adjust iris
Iris control is, as for the zoom and focus control, motorized, and is operated by the remote control or local
keypad.
