Conex™
CONNECT EASILY - CONTROL SIMPLY

With the increasing complexity of optical setups, the need for remote diagnostics and
control of repetitive tasks increases. Scientists and engineers recognize the benefits of PC
control of critical alignments, yet are often afraid of the effort, magnitude and cost
typically associated with the implementation of a computer controlled solution.
Newport’s new Conex™ product family addresses these concerns. Conex provides highly
functional control solutions that are easy to use, compact, and in-expensive. Available
today are the first three members of the new Conex family: The CONEX-CC DC servo motor
driver, the CONEX-PSD9 position sensing detector, and the CONEX-IOD I/O module.
Additional modules will be added soon.
Simple USB Connectivity
All Conex modules provide easy, plug-and-play, USB PC control.
Multiple units can be connected to a single USB port using
standard USB hub technology. Where possible, modules are
also powered through the USB port. No additional power
supplies or cables are needed, significantly simplifying cable
management and reduces accessory costs.
All Conex modules are 3.67" x 2.09" x 0.91" (93 x 53 x 23 mm) only. M3 inserts are provided on
three sides for flexibility in mounting. An optional adapter plate holds up to six Conex
modules, which mounts directly on optical tables.
Simple Control Software
A LabView based utility program provides a graphical user
interface (GUI) for each module. The GUIs are also
available as .llb components that facilitate integration into
custom LabVIEW programs.
A comprehensive set of LabVIEW VIs is available as well.
CONEX-CC
DC-SERVO CONTROLLER/DRIVER
The CONEX-CC is a very compact and inexpensive driver for Newport’s low power DC
servo motor driven devices. For out-of-the box control, the CONEX-CC is preconfigured and
delivered with the motion device. Available configurations include TRA and LTA Series
actuators, MFA linear stages, SR50 and PR50 rotation stages and BGS50 goniometers.
The linear amplifier of the CONEX-CC provides the optimum drive solution for low-power
motors. Compared to other solutions relying on cheaper PWM amplifiers, the CONEX-CC
delivers much smoother motion, with less electrical noise and significantly less motor
heating.
The motors are powered through a 24 VDC power supply, model CONEX-PS. For added
convenience, the power can be shared with up to 5 modules using the optional CONEX-PSCB power chain cable.

CONEX-PSD9
POSITION SENSING DETECTOR
The CONEX-PSD9 position sensing detector provides accurate XY position information of
laser beams and is ideally suited for laser beam stabilization, laser tracking and general
beam diagnostics. Unlike quadrant detectors, the improved tetra-lateral effect diode of the
CONEX-PSD9 is highly linear over the full sensor size of 9 mm x 9 mm, and delivers a third
signal that is proportional to the beam power.
Compared to many detectors that are tweaked for high bandwidth, the CONEX-PSD9 has
been optimized for stability and compatibility with pulsed laser beams. An analog input
filter with 319 Hz cut-off frequency suppresses high frequency noise and undesired signal
ringing when used with pulsed lasers. An additional digital low pass filter can be set by
software in a frequency range from 0 Hz to 1000 Hz to further improve signal homogeneity.
The 883-OH adapter allows mounting additional optics in front of the detector for stray
light reduction or beam attenuation. The CONEX-PSD9 is post mountable with metric and
imperial screw interfaces.
