Active Vibration Platform

Optosigma Active Vibration Isolation Platforms are standalone vibration cancellation units designed for placement under sensitive benchtop instruments, providing active isolation without the need for a full optical table. They address low-frequency building vibrations (0.5-5 Hz) that passive pneumatic tables cannot attenuate.

Active isolation mechanisms:
– Electromagnetic (voice coil) actuators: sense vibration with accelerometers or geophones; cancel with electromagnetic force; bandwidth up to 100 Hz
– Pneumatic active (servo-valve): compressed air-based; lower bandwidth but higher load capacity
– Feedback loop: real-time vibration measurement and cancellation; typical attenuation: -20 to -40 dB above 0.5 Hz

Platform types:
– Benchtop active platforms: small footprint (30×30 cm to 60×60 cm); designed to sit under a microscope, interferometer, or balance
– Rack-mount active platforms: for instruments in 19-inch racks requiring vibration isolation
– Custom load capacity: from 5 kg (light instruments) to 200+ kg (heavy optical instruments)

Features:
– Self-leveling: automatically maintains platform level despite load changes
– Air pressure regulation: built-in pressure regulator for pneumatic models
– Status display: LED indicators for isolation status and power
