NPS-Theta–2A Tilting 2 mrad Stage

NPS - Theta – 2A Tilting 2 mrad Stage

The Queensgate NPS-Theta-2A Tilting 2 mrad Stage has been developed for applications requiring ultra-high precision positioning of mirrors in optical inspection and imaging systems.

The mirror is simply fixed onto the tilting platform of the stage to provide > 2 milliradians of travel with sub micro-radian resolution. Low moving masses and optimized closed-loop control offer exceptional response times for high speed application. Flexible digital closed loop electronics allow response optimization to be performed in-situ.
