AVI Series: Removing Vibration Noise from Measurements

AVI Series Versus the Competition

AVI Series vibration control platforms offer excellent performance, functionality and reliability that is considered to be unparalleled across the industry today. For this reason, thousands of researchers across the globe trust Herzan to assist in the elimination of vibration noise from their measurements. 

This article outlines why researchers select the AVI Series over competing alternative solutions and how its novel features offer the best overall experience for any vibration control platform.

1. Unparalleled Vibration Control Performance

AVI Platforms offer the greatest vibration reduction of any platform available on today’s market (up to 50 dB), isolating vibrations at the lowest starting frequency (0.5 Hz).

Competing solutions cannot compare with the level of vibration reduction supplied, with some amplifying vibrations at the initial frequency for AVI Platforms. For these reasons, researchers trust the AVI Series to facilitate achieving the appropriate environmental specifications for their microscope.

2. Decentralized Heat Load and EMI Noise

Generating 9–27 W for a two-isolator system, AVI Platforms are the lowest-power active vibration control systems on the market. Competing solutions commonly generate up to 600 W, resulting in EMI noise issues and thermal drift when platforms and microscopes are situated in tight spaces or compact enclosures.

AVI Platforms also have the advantage of including an external controller for the majority of electrical components, meaning any heat and EMI noise generated is appropriately distanced from the microscope, no matter how minimal: this is not available in most alternative solutions.

3. Legacy of Results and Reliability 

The progression of AVI platforms has come a long way from the first active vibration control platform developed by John Sandercock of ‘Table Stable’ in 1976.

Since the emergence of AVI platforms, innovation has continued to evolve key features and sustain AVI reliability, which is why thousands of platforms support microscopes across the field today.

4. Low-Profile Design 

AVI Platforms have the lowest profile of any platform developed for larger microscopes (SEMs/TEMs), with alternative solutions increasing the profile of the microscope by 8 inches in some cases. AVI platforms also support many large microscopes by the underlying frame, increasing the profile of the microscope by 2 inches or less, a key benefit of the modular and scalable design.

5. Modular and Scalable Configuration

Therefore, AVI platforms can support microscopes of any size and load capacity because of the modular and scalable design capabilities.

Alternative solutions are typically static designs that meet the individual requirements of the microscope and generally too large for the microscope, which extends the total footprint and takes up much-needed space within the lab.
