Tuning fork and crystal12/21/2023 ![]() ![]() The tuning forks can also be actuated directly with an electrical signal. The smaller oscillation amplitudes makes it easier to perform various near field experiments as the tip spends most, if not all, of its oscillation cycle near the surface. The increased stiffness means that the probe will have higher force sensitivity. Tuning fork probes are also typically much stiffer and have smaller oscillation amplitudes than cantilever probes. The additional light from a laser deflection system can interfere with readings and photobleach samples, hindering the ability to take data. NSOM requires low light conditions for optimal signal to noise ratio. ![]() The use of a deflection laser can also be detrimental to some experiments. This also translates into a decrease in cost and size of the system because laser and PSD modules are not needed. The resonant probe only needs basic initial tuning a process which can be fully automated with commercially available products like the MadPLL ®. Laser alignment is not necessary which saves significant time and effort when exchanging probes. Resonant probe AFMs offers several advantages over the optical deflection methods. Bare tuning forks available in boxes of 20, tuning forks with tungsten tips available in boxes of 8. Our tuning forks are available in two sizes, and are shipped to you conveniently ready to use - "out of the can" - with the typical cylindrical housing removed. 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. 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). Near-field Scanning Optical Microscopy (NSOM).Also available with tungsten tips attached. ![]()
