Newport Corporation, a worldwide leader in laser and
photonic solutions that Make, Manage and Measure Light, introduces the new CONEX-AG-M100D,
a remote-controllable, piezo-motor-driven mirror mount with an integrated
2-axis absolute position sensor. It combines the high-angular position
sensitivity of the field-proven Agilis piezo-motor direct-drive technology with
exact position information from a novel, patent-pending, 2-axis, absolute
position sensor. While other piezo-motor mounts lack exact position information
and hence can only be used for adjustments, the CONEX-AG-M100D is capable of
repeatable or absolute positioning tasks. This capability is important in
scanning applications or when steering a laser beam to different positions
repeatedly is required.
In open loop, the MIM of the mirror mount is 2µrad over a
±0.75º range and in closed loop,the MIM is 0.001º with a bi-directional repeatability of
0.01º. With the absolute position sensor, the user can also save a position
into memory and recall that position upon start-up without having to rely on a
home or reference location. This is beneficial when a previously optimized beam
path must be re-established.
According to Beda Espinoza, Senior Manager, Motion, at
Newport Corporation, “Integrating the Agilis mirror mount and the CONEX
controller platform, both developed with simplicity in mind, makes the
CONEX-AG-M100D very affordable. Combined with the NSTRUCT Instrument Management software platform, setting up becomes
much easier, leading to less time wasted and a faster implementation of
experiments.”
