PVS-5.5 Parallelogram Voice Coil Stage

The PVS5.5 Parallelogram Voice Coil Linear Stage is a high performance compact positioning system. It was specifically developed for applications requiring both high precision and high-speed positioning over a short to medium stroke. The system is fully self-contained including a one axis stage, voice coil actuator and high-resolution feedback device. The PVS-5.5 Parallelogram Voice Coil Stage is well suited for optical focusing and other micro-positioning applications in markets such as semiconductor, medical, optical testing, scanning microscopy, circuit board assembly and micro manufacturing. The PVS5.5 configured with a analog position feedback sensor is directly compatible with the SCA615 Servo Controlled Amplifier.

With a dime-sized footprint, the PVS-5.5 Parallelogram Voice Coil Stage is a compact, high performance, positioning system specifically developed for applications requiring both high precision and high-speed positioning over a short to medium stroke. The PVS-5.5 is ideal for optical focusing and other micro-positioning applications in markets such as semiconductor, medical, optical testing, scanning microscopy, circuit board assembly and micro manufacturing.

Stage: The PVS-5.5 Parallelogram Voice Coil Stage is guided along a single axis by an infinite life, flexure linkage system. The use of flexures produces a light, friction-free package that allows it to be mounted vertically or horizontally and multiple sets of mounting holes
included for convenient mounting.

Voice Coil: Voice coil motors produce the least amount of electrical noise of any motor type available today and the PVS-5.5 uses a high force voice coil motor to move the stage. Moving mass has been optimized to be as light as possible for minimum response time because the voice coil motor adds no additional friction to the stage.

Positioning Feedback Sensor: The PVC-5.5’s sub-micron resolution linear displacement sensor has high bandwidth and low noise for precise and responsive movements. It uses a frictionless, non-contact optical technology and its small package maintains the compact nature of the system. Even the illumination source attached to the moving mass has extremely low mass to avoid limiting system performance.
