About Projection Lenses
This calculator helps determine the optimal lens type and positioning for LED screen projection mapping or rear projection systems.
Lens Types:
- Ultra Short Throw: 0.2-0.7 throw ratio - Very close to screen
- Short Throw: 0.8-1.3 throw ratio - Close proximity installations
- Standard: 1.4-2.1 throw ratio - Most common for general use
- Long Throw: 2.2-4.0 throw ratio - Large venue applications
Throw Ratio: The ratio of projection distance to screen width. Lower ratios require less space but may need more expensive lenses.
