Precision Laser Scanning has introduced an advanced, high speed, polygon scanner controller with many new features.

Polygon scanners historically run at a single working speed and use a motor controller with a low level TTL system interface. This simple scheme, implemented without a CPU, is adequate for imbedded applications like laser printers and product inspection.

Today, high speed polygon scanners are being used with high power and Ultrafast / USP lasers in material processing applications. These systems need control of the polygon scanner over a high-level interface. The PLS-32-010 advanced controller has USB and RS-232 interfaces for remote control. The on-board CPU can regulate the polygon at any speed without an external frequency reference. The CPU can also synchronize multiple scanners to work together. It has a sine wave drive for low EMI and highly precise rotation over a wide speed range. The high capacity drive can power large aperture facets at scan rates of hundreds of meters per second. The PLS-32-010 supports the Wood Pecker TM , Eagle Eye TM and Hawk Eye TM polygon scanner lines. Precision Laser Scanning is focused on providing high speed polygon scanners along with related optics and expertise to guide customers through successful integration.
