10736A Three Axis Interferometer

The Agilent 10736A Three Axis Interferometer is used in multiple axis applications where linear and angular control of the stage is required. It combines in a single package the functionality of an optical bench with multiple beam benders, beam splitters, and three interferometers. The interferometers split an incoming laser beam into three beams to measure linear distance, pitch and yaw, or linear distance, roll and yaw. Three linear measurements provide the basis for calculating two angular measurements. The inherent beam parallelism ensures that there is essentially no cosine error between the three measurements and also ensures angle accuracy for pitch and yaw measurements. Other characteristics include:

• High performance package saves setup time and improves system performance
• Simple multi-axis installation
• High angular resolution for better control
• Wide angle range
• Monolithic optics for maximized mechanical stability
• Pre-aligned fiber optic remote receiver mounting
• Referenced optics

The 10736A includes two shear plates to create 3 parallel beam paths, three cube corners, one reference mirror and two quarter wave plates.

The 10736A Option 001 bends one measurement axis.

The 10736A and 10735A are identical except for the measurement beam patterns.
