55280A Linear Measurement Kit 主要技術規格 Measurement range Up to 40 m (130 ft) with Linear Optics Up to 80 m (260 ft) with Long Range Option Accuracy Temperature range: 0 - 40ºC (32 - 104°F) E1738A Air Sensor: ±0.4 ppm In vacuum†: ±0.1 (±0.02) ppm † Vacuum accuracy is ±0.02 ppm if the 5519A/B laser head is calibrated to MIL-STD 45662A Resolution Linear optics (10766A): 1 nm (0.04 µin) Plane mirror optics (10706A/B) *: 0.5 nm (0.02 µin) High resolution plane mirror optics (10716A) *‡: 0.25 nm (0.01 µin) * Requires the 10724A Plane Mirror Reflector. Since alignment of these optics is much more sensitive than for linear optics, linear optics are recommended for general use. ‡ Aperture distance of 10716A is 12.7 mm, whereas 5519A is 11 mm. 敘述 The Keysight 55280A Linear Measurement Kit, used with the Keysight 5530 Laser Calibration System, includes the optical equipment needed to measure linear distance (displacement) and velocity. The kit contains a Keysight 10766A Linear Interferometer,
