Double-Beam Interferometer:

Double-Beam Interferometer:

Two parallel measuring beams are used to acquire two length values independently of each other. So it is possible to determine the position, angle and difference values simultaneously.

Benefits:

• Simultaneous length and angle measurement or differential measurement
• Beam distance selectable
• Combinable with plane mirror, cat-eye or hollow reflector

Technical Data:

• Measurement range: up to 2 m with plane mirror
• Angle resolution: 0.001 to 0.005 arcsec (depending on selected beam separation)
• Angle measurement with cat-eye reflector: up to ±5°
• Data Sheet
