Halcyonics Mod 2M Active Vibration Isolation supports with controller

The Halcyonics MOD-2 M (often referred to as the MOD-2 M) is a legacy active vibration isolation control unit, commonly used with older scanning electron microscopes (SEMs), such as those by Carl Zeiss, and other high-precision laboratory equipment. 

The technical specifications for the Halcyonics active vibration isolation technology (currently marketed under Accurion by Park Systems) generally include: 

Vibration Isolation Performance

• Active Isolation: Starts as low as 0.6 Hz (newer models) or 1.0 Hz (standard legacy units).
• Passive Isolation: Provides isolation for frequencies above 200 Hz.
• Isolation Efficiency: Typically -25 dB (94.4%) at 5 Hz and -35 dB (98.2%) at 10 Hz.
• Degrees of Freedom: Active compensation in 6 axes (all six degrees of freedom). 

System Response & Control

• Settling Time: Approximately 300 ms.
• Response Time: 0.5 ms.
• Actuators: Low-voltage electromagnetic actuators.
• Adjustment: Automatic load adjustment is standard on modern successors, though legacy MOD-2 M units may require manual setup for specific instrument configurations. 

Operational Requirements

• Power Supply: 100–250 V / 47–63 Hz; typically consumes 10–20 W (max 50 W).
• Compressed Air: Not required (the system is purely electronic/electromagnetic).
• Operating Environment: 15–40 °C (59–104 °F) with relative humidity up to 60%. 

Load & Interface

• Load Capacity: Depends on the specific isolation elements connected; typical configurations support loads from 120 kg to 600 kg.
• Diagnostic Output: BNC analog diagnostic output.
