SS-30 Flexure-Based Galvanometer


Ideal for Raster Imaging Applications

Features Capacitive Position Sensing

 

Nutfield Technology’s SS-30 Flexure-Based Galvanometer with capacitive position sensing, offers exceptionally smooth scanning. TNutfield Tech's SS-30 Flexure-Based Galvanometerhis moving-magnet galvo is ideal for the most challenging applications such as small scan angle, high-duty cycle raster imaging, and printing. Cross-axis flexures replace ball bearings such that errors due to rumble and lubrication are eliminated, enabling smooth scanning, and long service life.

The SS-30 Flexure-Based Galvanometer is intended for large mirrors with recommended aperture range of 20mm to 50mm. It is ideal for use the page scanner in raster imaging systems, having great smoothness at low velocity. It’s also great as a tracking scanner for viewing or marking moving objects or for stabilization in imaging systems.

When integrated with Nutfield’s QD-4000 servo amplifier, the SS-30 Flexure-Based Galvanometer Scanners deliver excellent speed and accuracy. Due to the spring force inherent in the flexure pivot, some scanning modes, such as large angle point and shoot, are not recommended.
