Mad City Labs offers quartz crystal tuning forks for scanning probe microscopy applications such as atomic force microscopy (AFM) and near-field scanning optical microscopy (NSOM). Each tuning fork has two electrical leads for connection to a driving oscillator such as the Mad City Labs MadPLL ® instant AFM and nanoprobe instrumentation .

We discuss various aspects of the quartz tuning fork, ranging from its original purpose as a high quality factor resonator for use as a stable frequency reference, to more exotic applications in sensing and scanning probe microscopy.

Quartz tuning forks have been widely used as force sensors in scanning probe microscopes. The anti-phase and in-phase eigenmodes of a tuning fork are involved during microscope operations. Dynamic characteristics of both eigenmodes are studied by experiments and finite element analysis simulations.

Sonic Energy Crystal Tuning Forks are made of the pure quartz crystals. They provide amazing, rich vibrational resonance - just perfect for meditation, yoga and relaxation.

Clear Quartz Crystal Tuning Forks offer a new way to deliver pinpoint accuracy of a specific vibrational frequency. They are stronger than a traditional metal alloy tuning fork. The frequency can be applied directly to acupressure points, or used along the spine to gently move energy.

Tuning fork crystals, or also known as wrist watch crystals, are one of the oldest crystal design used for time control in watches, clocks and nowadays in computers and other electronic equipment as Real Time Clock (RTC). These crystal units are being manufactured today in mass production in various package sizes and shapes.

Experiments with Quartz Tuning Forks Electromechanical Oscillators and Lock-in Amplifiers Many digital watches use tiny quartz tuning forks as their time-base. The natural frequency of oscillation of the tuning fork provides a stable frequency for measuring time. To both excite and detect these oscillations the piezoelectric nature of quartz ...
