Multi-axis positioners revisited
Newport's LP Series lens positioners provide two, three, or five degrees of precision positioning for optical components.

Newport Corporation has brought out the Solaryx 1600P laser scribing system, the latest addition to the Solaryx range of thin film photovoltaic laser scribing systems.

Spectra-Physics' Excelsior laser platform includes low-power CW lasers at 375, 405, 440, 473, 488, 505, 532, 561, 594, 635, 785 and 1064nm.
The z motion is accomplished without rotation of the lens by a knurled ring with a precision 80 thread per inch thread.
Five-axis x-y-z qx-qy models provide smooth x-y-z translation plus true gimbaling about two orthogonal, coplanar axes.
Five independent degrees of freedom allow you to accurately position an optic in any plane along any axis.
Newport has redesigned these mounts, adding a number of performance enhancing features.
Precise, 100 thread per inch adjustment screws with new knobs including an integral hex hole allow smooth adjustment with increased sensitivity.
A new zero-freeplay x-y mechanism ensures accurate positioning and enhanced long-term stability, without relying on grease to take up the clearance between sliding elements, thereby reducing drift over both time and temperature.
New independent locks for each axis of translation and rotation securely lock the mechanism, not just the actuator screws, maintaining stable optical alignment.
Engaging or disengaging each lock has negligible influence on the other axes.
The threaded central aperture accommodates optical retaining rings and a variety of optics holders for simple lenses, objective lenses, or other optics.
Each unit is supplied with two non-marring Delrin retaining rings and a 12.7mm optic holder.
LPLH Series optics holders allow quick interchange of optical components.
They are available in standard sizes for 6.35, 12.7 or 19.1mm diameter optics. Request a free brochure from Newport Spectra-Physics ...
