QS-30 Open Frame 2-Axis Scan Head
Nutfield Tech’s Most Powerful Open Frame for XY Applications
With recommended aperture range of 20mm to 50mm
Nutfield Technology’s QS-30 Open Frame Scan Head is comprised of two galvanometers with mirrors mounted in optimized XY configuration, two servo amplifiers (require mounting to heat sink, not provided), and galvo-to-servo cable sets. Open frame heads are used for fast and accurate beam steering in XY applications and are often selected where there is no desire to employ a scan lens to focus the beam to a small spot.
The QS-30 Open Frame Scan Head has two QS-30 moving magnet galvanometers which is a flexure galvo. It’s ceramic rotor reduces rotor inertia and increases rotor stiffness.
Nutfield Tech’s QS-30 Open Frame Scan Head features factory-set ±5 or ±10VDC analog inputs that produce ±22.5 degrees optical scan angles. The QS-30 OFH scan head is available in apertures ranging from 20mm to 50mm for a variety of wavelengths.
