The achievable ranges for different Raymax Fusion infrared illuminators are given below. The ranges shown indicate the maximum usable range of a single 850nm unit with a high performance camera. The figures given are for reference only. Distances achievable in practice will depend on a combination of camera, lens and infrared illuminator.

Please Note:

• The intensity of illumination due to a given source is inversely proportional to the square of the distance from the source.
  [See Inverse Square Law.]
• The use of an 940nm illuminator will decrease the range by approximately 45%.
• The use of two units will increase the maximum achievable range by approximately 40%.
