When considering the purchase of a new microscope, follow these three tips provided by Herzan’s technical team to guarantee optimal utilization, maximum magnification, and exceptional uptime for your microscope.
Implementing these tips saves time and money on retrofitting solutions when noise issues are discovered subsequent to the microscope being installed.
TIP 1: Understand the Environment Through A Site Survey
Site surveys can determine environmental local noise sources within a lab, accentuating the amplitudes of noise over a preferred frequency range.
Tools such as the WaveCatcher are typically used to capture measurement data for a site survey as they are data acquisition systems that are compatible with a range of analog sensors developed to conduct rapid, simple measurements.
Once the data is collated, site survey reports are created, comparing measured data with the total permissible noise for an instrument. The analysis and recommendations listed in a site survey help influence the type of mitigation solutions best suited for bringing the noise to appropriate levels.

TIP 2: Mitigate Local Noise Sources to Minimize Ambient Noise
If the results of a site survey determine that environmental noise within the lab is above the acceptable noise for an instrument, there are a couple solutions to consider.
1) Eliminate all equipment that generates noise:
While not always feasible, eliminating noise-generating equipment from the room is the most economical solution and can often fend off the necessity to purchase additional isolation equipment. When conducting a site survey, request measurements with specific pieces of equipment on and off to establish which items are contributing to the most noise in the room.
2) Isolate the noise generating equipment:
When it is not possible to relocate noise-generating equipment, isolating such equipment as an alternative can have a direct impact.
Whether passive isolators for vibrating equipment, an enclosure for scroll pumps, or a faraday cage to shield a UPC; ensuring the noise generating equipment has been effectively isolated can help limit the overall ambient noise of the room
TIP 3: Support Microscope with Environmental Control Solutions
It is not always possible to decouple environmental noise from the room, necessitating effective noise canceling solutions to the measurements.
Ranging from cost-effective table-top enclosures and vibration control tables to large-scale state-of-the-art active vibration control platforms, Herzan specializes in alleviating all forms of environmental noise for precision microscopes.
