The light generated by an IRED is directly proportional to the forward current flowing through the device. Various biasing schemes
Almost all applications have an optical geometry containing a detector of a certain physical area that intercepts a portion of
Light sources vary widely in their spectral output and characteristics, with incandescent lamps acting as black body radiators, whose color
Care must be taken in the handling and soldering of all opto components, especially those that use a cast or
Infrared Emitting Diodes (IREDs) are solid state light sources emitting in the near infrared part of the spectrum. The emission wavelength is
The on-axis power emitted by an IRED is measured by placing a detector, with a given active area, at some
A wide angle IRED distributes its radiant flux as shown below. Most of the flux impinges on the lens surface
