Splitting And Bending - HP 5501A Operating And Service Manual

2.9 Splitting and Bending Optics (Figure 2-9)
The splitting and bending optics consist of the following units:
10700A 33% Beam Splitter
10701A 50% Beam Splitter
10707A Beam Bender
These 2 5 mm (1 inch) cubes are designed to allow a portion of the laser beam of the 5501A
Laser Transducer to be directed along each measurement axis. Since they are to be mounted
within
a machine, they are designed for ease and flexibility in mounting and for durability.
The Model 10700A 33% Beam Splitter deflects about one-third of the laser beam intensity at
right angles to the original beam direction, allowing the remaining two-thirds to continue.
The Model 10701A 50% Beam Splitter deflects half of the laser beam at a right angle and
passes the remaining half. Combinations of these two accessories allow some flexibility in
directing the desired fraction of beam intensity to each axis of a multiaxis configuration. For
example, using first a 33% and then a 50% Beam Splitter, one can direct one-third of the laser
beam intensity to each measurement in a three-axis machine.
The Model 10707A Beam Bender contains a 100% reflectance mirror which turns the direction
of an incoming laser beam at a right angle. It is mandatory that only right-angle turns be used
in routing the beam of the 5501A Laser Transducer within a machine.
