Depending on your application, we can probably provide you with what you are looking for.  MTI have some designs available that we have used in picoprojector applications to display video images. A single-axis device with a 0.8mm mirror has ~20kHz resonance and can do +/-8 degrees of mechanical scanning (+/-16 degrees optical). The same device resonates around 10kHz with a 1.2mm mirror. It is usually best to discuss such less standard requirements with us in person.
