is a measurement of the average apertured radiant energy incident upon a sensing
area 0.250" (6.35 mm) in diameter, perpendicular to and centered on the mechanical axis of
the lens, and 1.429" (36.3 mm) from the measurement surface. E

Description
The OP294 and OP299 are gallium
arsenide infrared emitting diodes
designed for low current or power limited
applications (such as battery supplies).
These LEDs are similar in design to the
OP290 and OP295 but use a smaller
chip which increases output
efficiency at low current levels by
increasing current density. Light output
can be maximized with continuous (d.c.)
forward current up to 100mA or with
pulsed forward current operation up to
750 mA. The chip is mounted in an IR
transmissive plastic package and has
been designed and tested for use with
OP593/598 phototransistors or similar
photodetector.
