Notice to Installer:
Please use the following installation instructions to obtain superior optical performance from the Polar
Star® Angular Reflective ALR
(Ambient Light Rejecting)
Screen.
Make sure to follow these instructions in order for the Polar Star® to perform correctly.
•Angular-Reflective material is not compatible with ultra/short-throw projectors
•Minimum lens throw ratio 1.5x image width
•Ambient light must not come from the same direction as the projector
Since angular-reflective means that the projected image will reflect at the mirror-opposite angle, it is
important to position the projector so that the viewer will get the best possible image.
Step 1:
Establish the general “eye level” of the viewers
Step 2:
Set the appropriate projection level
Step 3:
Adjust the screen height level and projection angle
Input Angle
(A) = Output Angle (B) aligns with the viewer’s angle
