Shutter Mechanism
For units with a shutter mechanism, the shutter is comprised of four frame blades that move
independently or in unison. The entire assembly operates in a smooth, time-continuous motion using
stepper motors (two per frame blade and one to rotate the entire shutter mechanism). The shutter
mechanism can rotate 45
o
in either direction and the frame blades can tilt +/- 35
o
.
