| Light Meter: The light meter measures the intensity of the light at the location of its detector. You can place up to three light meters anywhere in the simulation window. An alternative view of this object is available. Note: Light meters are only strictly accurate for point sources. Linear and complex sources are treated as point sources located on the central axis. In this simulator, light meters do not work if any of the following elements are placed in the simulation window: mirrors (off-axis), triangular prisms, rectangular prisms, or two-media elements. In addition, light meters do not detect light coming from beam projectors.
