Acoustic and Vibration Isolation
For Asylum Research AFMs
Isolation from the lab environment plays an important role in image and measurement quality. Our AFM systems inherently have some of the lowest noise specifications in the industry, however, Asylum Research offers a variety of isolation tables and integrated acoustic enclosures that will optimize your AFM’s performance in noisy environments. Vibration isolation is required for all MFP-3D™ AFM systems and is optional for the Cypher™ AFM. Because each facility environment is different, we recommend prospective users evaluate their available options. As a courtesy to our customers, Asylum Research can provide a site survey kit to quantify the vibration and acoustic noise of your lab prior to your system installation.
Acoustic Isolation Enclosures
Two different models of enclosures are available for the small and large footprint MFP-3D systems. The enclosures provide excellent acoustic protection, low frequency passive vibration isolation and protect your instrument from air currents. The frame is made of powder-coated steel tubing. The chamber has a powder-coated steel exterior and a proprietary layered interior which provides the ultimate in sound insulation over a wide frequency range. Each enclosure is designed with a front window, an adjustable stand inside for resting the MFP-3D Head while changing cantilevers, two side cable clamps, swiveling casters, and leveling feet. Contact Asylum Research for choices of compatible vibration isolation tables and their dimensions.
Options for Acoustic Isolation Enclosures
1) Air Temperature Control – Minimize drift with the AEK and BCH enclosures
The ATC system keeps the air temperature inside of the hood constant around the instrument regardless of the laboratory temperature. A quiet fan draws air into the bottom of a vertical duct in the hood, then forces it through a series of heater coils and expels the warm air above a porous false ceiling which creates a plenum above the AFM. The warm air uniformly flows downward over the microscope where temperature feedback sensors, typically placed near the AFM head and scanner, monitor the hood temperature. The ATC simply plugs into the expansion port in the ARC2™ or MFP-3D AFM system controller. Fan speed, temperature setpoint, ramp rate, and heater power are easily controlled through the software interface. (Contact Asylum Research for current specifications and current user upgrades.)
2) BCH-45 Optical Window
3) BCH-45 Extra Ports
Vibration Isolation Tables
Asylum offers two series of vibration isolation tables, the Herzan AVI Series and the Table Stable Series. Either will fit nicely in the matching acoustic enclosures. We recommend the AVI-SA for the MFP-3D Stand Alone and the AVI-BIO for the MFP-3D-BIO.
