Projection Calculator

Please note: The results shown are approximate values. In reality the results may differ slightly. The calculation applies under the following conditions:

  • The projection motif is circular and fills the image area of the gobo. Other shapes and objects, e.g. rectangles or fonts, are fitted into this maximum projection area.
  • The projection is at right angles to the projection surface.
  • The projection surface is a plane.
  • The distance is measured between lens and projection surface.
