Description
Atomfair PCI 571 Piezoelectric Ceramic Interferometry Measurement Instrument
Product Overview
Atomfair PCI 571 Piezoelectric Ceramic Interferometry Measurement Instrument adopts Michelson interferometry to accurately measure the piezoelectric constant of piezoelectric ceramics and the frequency response characteristics of their vibration. The instrument adopts a new platform-type structural design, making adjustment and measurement operations more convenient. It is a core optical instrument for observing various optical interference phenomena and verifying relevant basic theories in physics experiments of institutions of higher education, suitable for physics teaching and engineering optics experiment scenarios.
Instrument Features
- Light Source: He-Ne laser with wavelength 632.8nm, power ≥1.5mW, single-mode TEM鈧€鈧€, equipped with fully protected safety high-voltage plug, cavity length 250mm.
- Piezoelectric Ceramics: Tubular structure with electrodes plated on inner and outer walls respectively for easy voltage application.
- Structure: New platform-type Michelson interferometer design, easy to add measured substances in the optical path; open space makes it easier to adjust equal-thickness interference, equal-inclination interference and various fringe changes, supporting precise measurement.
- Base: Cast iron base is used as the experimental platform to ensure stable and reliable experimental process and reduce external interference.
