Keysight / Agilent 10774A Overview

The Agilent 10774A Short Range Straighness Optics combines a straightness interferometer and reflector to make measurements over a range of travel up to 3 m (10 ft). The optics form a highly-accurate optical straightedge that can measure the straightness of travel of machine-tool and measuring-machine coordinate motions with a resolution of 0.04 micrometer (1 uin).

The Agilent 10774A, used in the Agilent 5529A calibration system, is one of a large selection of components that tailor interferometer systems for the physical layout and measurement requirements of each application.

Features:

• Straightness Measurement Accuracy
• Overall Accuracy = Optical Reference Accuracy + Measurement Accuracy.
• This is analogous to the traditional straightedge and indicator method of measuring straightness, where Optical Reference Accuracy corresponds to the straightedge accuracy, and Measurement Accuracy corresponds to the indicator accuracy.
• Optical Reference Accuracy
• Optical reference inaccuracy can be eliminated by using straightedge (mirror) reversal techniques.
• Metric units mode: 0.15 M² µm
• English units mode: 0.5 F² µin
• Measurement Accuracy
• Temperature Range Displayed Value: 0 µm to 10 µm 10 to 1,500 µm
• 0 µm to 400 µm 400 to 60,000 µm
• 15° C to 25 °C ±3.5% ±1% ±0.25 µm (10 µin)
• 0° C to 40° C ±6% ±1% ±0.5 µm (20 µin)
• Straightness Measurement Resolution
• Agilent 5519A, Agilent 5519B , Agilent 5518A
• Short Range: 0.01 µm (0.4 µin) 0.04 µm (1.4 µin)
• Straightness Measurement Range (Orthogonal to Axial Travel)
• ±1.5 mm (0.060 in)
• Axial Separation (Travel)
• (distance between the interferometer and the reflector, typical, with proper alignment, 15° C to 25° C):
• Short Range Optics: 0.1 m to 3 m (4 in to 120 in)
• High resolution plane mirror
• More accurate and lower sensitivity to air turbulence than alignment lasers
• Available separately or as part of the Agilent 55283A Straightness Measurement Kit
