The Latest Innovations in Environmental Control
Herzan’s products evolve over time to adapt to modern research needs. These changes are motivated by researcher feedback, enabling the Herzan team to discover changes best suited to improve the performance, accessibility, and reliability of products. The latest entries showcase recent improvements to Herzan’s most popular products, including the AVI Series active vibration control platforms, AEK acoustic enclosures, and SEM acoustic enclosures.
Keeping Temperatures Stable for SEMs in Herzan SEM Enclosures
With the advancement of electron microscopes, sensitivity to acoustic noise becomes more prevalent, often requiring an acoustic enclosure to insulate from ambient lab noise. When enclosing an electron microscope inside an acoustic enclosure, managing internal temperatures is key to prevent the detrimental effects of thermal drift.
Herzan’s dynamic solution for heat dissipation maximizes the heat exhausting from the acoustic enclosure, while minimizing the air circulating inside the enclosure, and noise entering the enclosure. (See diagram above.)
Stacking Two AVI Platforms Offers 75 dB Reduction
While the AVI Series currently provides industry-leading, low-frequency vibration control, the R&D team at Table Stable demonstrated the incredible benefit of stacking active isolation systems, showing the dramatic difference in vibration control performance between passive, active, and a double-stacked active isolation systems.
Further improvement to the performance of a standard or double-stacked active isolation system can be seen when adding an LFS System, which improves the low-frequency isolation performance of any AVI Platform.
Depicted in the graph below:
- Blue (Passive): AVI-200 with Active Isolation Disabled
- Yellow (Active): AVI-200 with Active Isolation Enabled
- Red (Double-Stacked Active): AVI-200 placed on top of an existing AVI-200 and top plate; both having Active Isolation Enabled
Measured Benefit of Double-Stacking Active Vibration Control Platforms
Upgraded Cable Clamps Reduce Sound Entering Herzan Enclosures
Herzan acoustic enclosures maximize accessibility for the researcher, while minimizing incoming acoustic noise and airflow. Due to the diverse projects supported over the years, upgrades have been introduced to support these three design goals.
The most recent upgrade improves how customers port cables out of the enclosure, now tailored to the diameter and quantity of cables used for each instrument. This new approach ensures researchers can securely install their instrument inside a Herzan enclosure, while not being impeded by airflow or local noise. (See photo below.)
There are many different cable port penetration points to choose from
when optimizing the enclosure for your research application.
