PI offers a large range of Ultra-Fast Piezo Tip/Tilt Platforms specially designed for active and adaptive optics applications. Providing a very large tilt range of up to 50 milliradians, fast response (down to sub-millisecond range) and sub-microradian resolution, the systems are ideal for dynamic operation (e.g. tracking, scanning, drift and vibration cancellation, dithering, etc.) as well as static positioning of optics and samples.
