Agilent/Keysight 10774A

The Agilent/Keysight 10774A is a short-range straightness optics accessory that integrates a straightness interferometer and reflector to measure straightness of travel for machine tools and measuring machines. It establishes a highly accurate optical straightedge for precision linear motion analysis over distances up to 3 m (10 ft), making it essential for metrology applications demanding sub-micrometer straightness characterization.

– Technical Specifications

• Measurement Type: Straightness of travel
• Axial Separation Range: 0.1 m to 3 m (4 in to 120 in)
• Straightness Measurement Range: ±1.5 mm (0.060 in) orthogonal to axial travel
• Resolution: 0.01 µm (0.4 µin) and 0.04 µm (1.4 µin)
• Measurement Accuracy (15°C to 25°C): ±3.5% for 0–10 µm and 0–400 µm; ±1% for 10–1,500 µm and 400–60,000 µm; ±0.25 µm (10 µin) offset
• Measurement Accuracy (0°C to 40°C): ±6% for 0–10 µm and 0–400 µm; ±1% for 10–1,500 µm and 400–60,000 µm; ±0.5 µm (20 µin) offset
• Optical Reference Accuracy: 0.15 m² µm (metric); 0.5 ft² µin (imperial)—eliminable via straightedge reversal techniques
• Mounting: High resolution plane mirror

– Key Features

• Modular design enables integration within Keysight laser calibration systems such as the 5530
• Mirror reversal techniques allow elimination of optical reference inaccuracy for improved absolute accuracy
• Operates over extended temperature ranges with well-defined accuracy specifications at both 15–25°C and 0–40°C conditions

– Typical Applications

• CNC machine tool straightness characterization
• Coordinate measuring machine (CMM) axis alignment and validation
• Precision spindle and bearing runout assessment
• Linear stage and guide rail performance verification

– Compatibility & Integration

The 10774A integrates with Keysight laser heads including the 5519A and 5519B. Typical measurement setups require an interferometer target (P/N 10774-67001) and reflector target (P/N 10774-20021). The accessory is available standalone or as part of the 55283A Straightness Measurement Kit, functioning as a plug-in optics module within Keysight’s modular laser interferometer architecture.
