Raising the Precision Ceiling of Scientific Research: The Value of JMZ-TK in Precision Measuring Instruments
In cutting-edge scientific research, measurement precision often determines the upper limit of new discoveries. Equipment such as scanning electron microscopes (SEM), atomic force microscopes (AFM), lithography machines, and gravitational wave detection devices are sensitive to environmental vibrations at the nanometer or even picometer level. The JMZ-TK series vibration isolators from Xi'an Hoan Microwave are precisely "ultra-quiet platforms" tailor-made for these cutting-edge scientific research instruments that pursue extreme precision.
The requirements for vibration isolation systems in these instruments are extremely stringent: they must not only isolate medium-to-high frequency vibrations, but also effectively address ultra-low frequency (<1Hz) ground microtremor noise. The JMZ-TK series perfectly meets this challenge through the combination of its low natural frequency design and high damping characteristics.
Combating Ground Microtremors: Through optimized design, its vertical natural frequency can be as low as 3-5Hz or even lower, enabling effective isolation of the main frequency band (1-20Hz) of ground microtremors.
Suppressing Internal Microvibrations: Microvibrations are also generated by internal components of high-precision instruments, such as scanning mechanisms and vacuum pumps. The high damping of JMZ-TK can quickly attenuate the transmission of these internal vibrations, preventing resonance from forming inside the instrument structure and interfering with measurement signals.
When researchers place samples under an electron microscope to observe atomic structures, or when a lithography machine etches nanoscale circuits on a silicon wafer, the JMZ-TK builds a nearly absolute static reference frame beneath the equipment. It eliminates image blurring, measurement drift, and circuit jagged edges caused by vibrations, directly improving the equipment’s ultimate resolution and repeat measurement precision. It can be said that the JMZ-TK series is an unsung hero that helps scientists explore the unknown and expand the boundaries of human cognition.
