Projection Planner 2.0

Footcandle & footlambert image

Projection Planner 2.0 has been updated using the latest InfoComm standards and best practices to help you identify the best projection viewing surfaces for your specific application.

Calculations using the AVIXA Projected Image System Contrast Ratio (PISCR) Standard help balance projector brightness, room lighting, and screen surface for a clear image with good contrast. Calculations using the AVIXA Display Image Size for 2D Content in Audiovisual Systems (DISCAS) Standard define the optimum screen size for the application.

How to use the Projection Planner 2.0

While we have attempted to make this powerful tool informative and easy to use, it cannot replace the expertise of a Draper representative. Please contact us if you have any questions.

Glossary of terms

fL: Footlambert - A footlambert is the measurement of brightness of one square foot from the illuminated screen.
CR: Contrast Ratio - The ratio of the luminance of white to black. An ANSI contrast ratio is done with a checker board patterned test image where the black and white luminosity values are measured simultaneously.
Half Gain Angle: Half Gain Viewing Angle
Min. Throw Distance: The minimum distance between the projector and surface recommended to maintain focus and white field uniformity.
Element Height (EH) %: Height of an element in relation to the overall image height (refer to AVIXA DISCAS Standard)
