NEC Projector Image and Lens Calculator

With this tool you can:

  • Calculate the possible image size (width, height, diagonal) for a given distance (distance)
  • Calculate the necessary projection distance (distance for wide angle and telephoto lens) for a given image size (width, height, diagonal)
  • If you already know the projection distance you can optionally filter the respective lens result

Please note that the calculated values may differ slightly from the real values due to mathematical rounding (+/- 5%).
The calculation is performed for each interchangeable lens appropriate to the selected NEC projector.
