The QS-7 /10 has faster step response and higher signal-to-noise position detection compared to any scanner in its class. The QS-7/10 offers tremendous torque in a small outline. This means it can be packaged into a smaller volume and still provide peak performance. The Patent Pending ceramic rotor design has exceptionally low inertia and high stiffness, which results in higher bandwidth performance. The QS-7/10 Position Detector was designed with a high-output feedback signal for the best possible accuracy. NTI galvanometers have three times greater signal-to-noise; the highest in the industry. This means greater pointing accuracy and repeatability in your application.

5 QuantumScan-30 Moving Magnet Galvanometers Nutfield Technology's QS-30 uses exotic materials and an innovative architecture to provide industry leading performance. The QS-30 has faster step response, higher signalto-noise position detection and improved thermal management compared to any scanner in its class. The Industry s First Ceramic Rotor For Faster Step Response Thermally De-Coupled Stator For Lower Drift SLR Stator Design For Higher Bandwidth Position Detector With Signal / Noise >100,000:1 sales.info@nutfieldtech.com NTI continuously performs research to improve scanner performance so that your products remain competitive in the marketplace. This research has lead us to a patent pending ceramic rotor design. This first of a kind rotor has exceptionally low inertia and high stiffness, which results in higher bandwidth performance. The QS-30 Position Detector was designed close to the mirror for the best possible accuracy. Further position detector refinements give NTI galvanometers up to 8 times greater signal-to-noise; the highest in the industry. This means greater pointing accuracy and repeatability in your application. The galvanometer s stator is thermally isolated and located far away from the position detector. This reduces thermally induced drift; a patent pending feature found only in NTI galvanometers. QuantumScan-30 For mm Beam Apertures Another breakthrough is our stator design, which is the first to incorporate Side Load Reduction (SLR) technology to reduce off axis magnetic forces on the rotor. The benefit is higher bandwidth and faster step response resulting from less stator induced side forces.

7 SilkScan-30 HarmonicScan-15 Cross Flexure Pivot Suspension Moving Magnet Galvanometers Nutfield Technology s Flexure Galvanometers have lower cross axis wobble, higher signal-to-noise position detection and faster step response than other flexure scanners in the market. They operate just like a galvanometer with a constant spring force attached to the rotor. SilkScan-30 For mm Beam Apertures Excellent For Raster Scanning, Imaging, Repetitive Small Angle Or Military Applications Flexures Eliminate Ball Barings For Long Life & Smooth Scanning No Lubrication Means No Outgas Or Vapors High Signal / Noise Position Detection Sales.info@nutfieldtech.com NTI flexure galvanometers use cross flexure pivots instead of ball bearings. Flexures are superior to bearings in several ways including long service life. Our flexures are constructed from high quality stainless steel spring material with an endurance rating over 100 kpsi. Our scanners run at low stress levels, typically less than 10 kpsi. They operate in the "infinite life" portion of the stress curve. This means that these units can run continuously for many years. Flexure pivots scan smoother because there is no rolling friction or surface finish issues between the balls and raceways. The most demanding raster imaging systems use flexures because of their excellent smoothness and repeatability. Flexure galvanometers have no lubricants; so there is not an issue with out gassing, which is important in some vacuum applications. Ball bearings are designed to rotate through large enough angles to sufficiently distribute lubrication HarmonicScan-15 For 7-15 mm Beam Apertures within the bearing. Several problems can arise when a ball bearing is used in a galvanometer. Lubricant can be displaced from the contact area when the scan angle is small, causing the balls and raceways to wear. Flexure based galvanometers are not appropriate for all applications. Call our experienced team for assistance in selecting the appropriate galvanometer for your application.

Applications where the command signal keeps the mirror positioned away from center by more than 7 degrees optical, for extended periods of time, could cause over heating due to the spring force of the flexures.
