	Description
	In this subchapter refers to either or both of the Agilent 10737L and
NOTE
	Agilent 10737R interferometers.
	The Agilent 10737L/R Compact Three-Axis interferometers (see
	figures 7O-1 through 7O-3) allow up to three measurements
	(displacement, pitch, and yaw) to be made on a single axis. The
	Agilent 10737L and Agilent 10737R interferometers are identical
	except that the “L” bends the measurement beams to the left and the
	“R” bends the beams to the right, as viewed from the incoming beam
	(see figures 7O-2 and 7O-3).
	These interferometers are designed to use a 3 mm diameter laser
	beam, available from an Agilent 5517C-003 Laser Head.
	The measurement beam parallelism inherent in the design of the
	Agilent 10737L/R interferometers ensures that there is essentially no
	cosine error between their three measurements and also ensures angle
	accuracy for pitch and yaw measurements.
	These interferometers are designed for direct attachment of
	Agilent 10780F-037 Remote Receiver’s fiber-optic sensor head (one per
	axis). The Agilent 10780F-037 receiver is the same as the standard
	receiver, except it does not include the lens assembly that attaches to
	some Agilent interferometers; in this case, the required lens assembly
	is part of the Agilent 10737L/R interferometer. This simplifies user
	assembly, since no optical alignment of the receiver is required. The
	fiber-optic cables from the receivers attach directly to the axis output
	apertures on the input face of the interferometer. See figures 7O-2 and
	7O-3.
	The Agilent 10737L/R interferometers are based on the
	Agilent 10706B High-Stability Plane Mirror Interferometer’s design.
	Figure 7O-1 shows two views of an Agilent 10737L interferometer. In
	addition to the Agilent 10706B components, the interferometer
	includes the following assemblies:
	• The receiver assembly. This can be removed during alignment
	using the 4-40 socket-head cap screws. The 4-40 button-head
	screws hold the 0.100-inch-thick cover plate and the receiver
	assembly parts in place; do not try to loosen these screws or remove
	the plate.
	• The shear plate assembly. This assembly is factory-aligned and
	must not be loosened or removed.
