PI V-308 Voice-Coil Vertical Linear Stage
PI V-308 Voice Coil PIFOC Objective Focus Drive
V-308 is a vertical objective-focus positioner with a voice-coil motor, crossed-roller guide and adjustable magnetic weight compensation. The current V-308.753030 specification provides 7 mm travel with user-adjustable travel limitation and compensation for a load up to 1 kg under the documented orientation. Objective holders and adapters must be specified separately.
Review Summary
Consider V-308 for fast microscope focus or surface inspection when the objective mass and optical geometry fit its load and travel. Its 1 nm feedback resolution is separate from 10 nm minimum incremental motion and from travel-wide positioning accuracy. Small-step settling figures apply only to their stated step and error band.
