High-Performance LED
Test Equipment
The strictly defined 850 nm wave-
length and high power is ideal for test
equipment applications. It is pack-
aged in a hermetically sealed can for
high reliability and maximum resis-
tance to harsh operating environments.
The double-lens optical system
results in optimum coupling of power
into the fiber.
