Page 4 Fall 2006Product SpotlightGTS SeriesHigh Precision Linear StagesSuperior performance in repeatability,accuracy, straightness, flatness,pitch and yaw.Key FeaturesTrajectory accuracy compatiblewith ESP300 and SMC100CCmotion controllersUltra-quiet anti-creep crossedroller bearingsIntegrated linear encoder with50 nm resolutionVery low friction ball screw drive70 mm and 150 mm travelsThe GTS high-precision linear stagesprovide high sensitivity andoutstanding trajectory accuracy in acompact and robust package. Theyare an excellent solution forapplications such as surfacescanning, test and calibration,optical component alignment andattachment, and high-precisionoptical delay lines.XPS Motion ControllerollerNewport's GTS stages are machinedfrom stress-relieved 7075 aluminumensuring long-term strength andstability. The advanced asymmetricbody design with defined flexiblepreload provides consistent resultsover varying temperatures. The T-shape carriage is further optimizedfor different load conditions.To ensure accurate trajectorycontrol, GTS stages use matchedpairs of anti-creep crossed rollerbearings. A high-torque DC motorand a low friction ball screw driveeliminate stick-slip effects andensure ultra-smooth motion with100 nm sensitivity. Precision positionfeedback is provided by an opticalscale with 50 nm resolution. Theoptical scale is mounted in thecenter of the stage to eliminate alldrive-train induced motion errors.The normal centered load capacity is100 N and the max. speed is 50 mm/s.See our website for more info.WEB newport.comNewport’s s XPS Brushless Motor Initialization AlgorithmWins a Corporate Innovation AwarAwardNew algorithm reduces induced oscillations to insignificantamplitude.Newport’s XPS motion controllernow features a new algorithm forthe necessary initializationprocedure of brushless motors.Brushless motors are used in many ofNewport’s advanced linear stages,rotation stages and highperformanceair-bearing systems.The purpose of motor initializationis to define the position of themotor coils to the magnets. Mostbrushless motor initializationprocedures take a long time tocomplete, induce high amplitudeoscillations, or require dedicatedhardware such as expensive Hall-Effect sensors. The new costeffectiveNewport solution reliesonly on the smart and optimal use ofthe existing XPS electronicshardware. The motor coil position isaccurately determined through aseries of imperceptible motions,which significantly reduce theinitialization time.This patent pending invention wasawarded a Corporate InnovationAward during the ConferenceInternationale Francophoned’Automatique, an IEEE event thatgathered researchers in theadvanced domains of motioncontrol, in Bordeaux, France, lastJune. This Award recognizes thenovelty of the algorithm to solve arather challenging issue and theconclusive results of a long andintimate collaboration of Newport’ssubsidiary in France, MICRO-CONTROLE Spectra-Physics S.A, witha leading French electricalengineering laboratory.See our website for more info.WEB newport.comwww.newport.com
Fall 2006 Page 5Oriel LED SourcesCompact and Economical Alternatives to Lamp Based SourcesNew series outperforms traditional CCD-based instrumentsNewport’s new Oriel LED Sourcesprovide either narrow or broadbandradiation via an 8 mm Liquid LightGuide (LLG). These sources areeconomical alternatives to diodelasers and QTH lamp-based systems.A manual shutter with anintegrated filter holder is availableas an option for the end of the LLG.The intensity can be varied and anexternal trigger can be applied tomodulate the source on and off.Additionally, the LEDs have anaverage lifetime in excess of 40,000hours of continuous operation. Weoffer various narrowband modelscovering the 395 nm to 800 nmspectral range, with bandwidths of ~22 nm, and a broadband VIS model.Key Features395 nm to 800 nm with ~ 22 nmbandwidths, or a broadband VISmodelHigh intensity, 0.4 ~ 0.66 W lightguide coupled outputVariable intensity outputExternal triggerSee our website for more info.WEB newport.comwww.newport.com
