LASER ALIGNMENT FIXTURE ASSEMBLY
The laser alignment fixture assembly consists of a low power helium-neon laser
and a laser power supply.
The laser is used when alignment of the mirror assemblies
in the dayside test bench is being performed.
It is attached to the laser mount
inside the laser protective cover assembly.
It transmits a precise beam of laser
energy through the beamsplitter and laser fold mirrors inside the test bench into
the CID camera.
The CID camera converts the received laser energy into electrical
signals that are displayed on an oscilloscope.
The third fold mirror is adjusted in
the horizontal and vertical directions as necessary until the laser energy is
centered in the CID camera.
