Applications include very high power laser entertainment displays. The Saturn 9B is capable of moving a 10mm beam through an optical angle of 40° at a frequency of over 500 Hz with a sinusoidal drive. Step response times with a 10mm beam can be lower than 300 microseconds for a small optical step, and 1 millisecond for a 40° optical step, delivering scanning speeds of ILDA 30K / 2.5kHz small signal bandwidth, even with a large 10mm beam. The new -46S and -56S versions utilize coil configurations optimized for small-signal and large-signal applications respectively, both of which further reduce heat generated by the scanner as well as the servo driver. In addition to its high-speed and large-beam capabilities, the Saturn 9B incorporates several very desirable design features. First, because of its half-inch-round body dimensions, the Saturn 9B is easily retrofitable into many existing systems. Second, the integral back-supporting mirror mount helps to control “diving board” bending-mode mirror resonances while also easing field replacement of mirrors. And finally, the high-output, low-noise position detector enhances short-term repeatability and minimizes dither. The patented X3 magnetic circuit boasts air gap flux densities of over 14,000 Gauss. The intense magnetic field strength, combined with the low coil resistance and relatively low rotor inertia, gives the Saturn 9B the highest RMS-torque-to-inertia ratio of any commercially-available optical scanner capable of moving a 10mm beam.

Other factors may prevent the scanner from reaching this maximum, such as servo driver and power supply. 2. Angular specifications are in mechanical degrees. For most applications, optical angle = 2x mechanical angle. 3. Saturn 9B versions -46S and -56S use different coil configurations, beneficial in certain imaging applications. Saturn scanners can easily be fabricated with alternative coil configurations to achieve different...
