Description

The Hummingbird mini-positioner is a compact device designed for the ultra high speed positioning of low mass payloads. Developed for a contact and non-contact probing of planar objects, it can probe at over 50 cycles per second with accelerations exceeding 50 Gs The five bar linkage of the mini-positioner covers a 13 millimeter square workspace. To reach larger positions, the entire mini-positioner can be moved. The two main links are driven by high performance moving coil actuators, and the link positions are sensed by low mass optical encoders. ...
