PSH series/mirror tilting systems
PSH 4/1
Product Description
The piezoelectrical mirror tilting systems of the piezo mirror tilting and scanning platform PSH 4/1 is designed for ultra fast positioning tasks with nanometer accuracy. It is well suited for beam steering, scanning applications, vibration control, beam alignment and beam tracking tasks.
The PSH 4/1 was developed as an ultra fast scanning system for kHz frequencies. The miniature system is based on two active actuators. It provides ± tilting with a total travel range of up to 4 mrad. Because of the internal pre-load, the system shows a very short settling time and the resonant frequency is greater than 6.5 kHz when unloaded.
Because of the special flexure hinge design (FEA calculated) the system is free of friction and mechanical play. The piezo mirror tilting and scanning platforms PSH 4/1 is available in cryogenic and vacuum versions. Optical components such as mirrors can be mounted directly on top of the system plate.

FAQ
How do I choose between open-loop and closed-loop versions?
Choose closed-loop when you need absolute positioning accuracy and repeatability (e.g. measurement, alignment). Open-loop is more cost-effective and responds faster when you only need relative fine motion or scanning, or when your system already has its own feedback.
Can I test the unit before deciding?
Nahshon is the exclusive distributor of piezosystem jena in Taiwan and keeps commonly used demo units available for scheduled testing, with Chinese-language selection support and direct access to factory engineering.
How do I confirm pricing and lead time for PSH 4/1?
Add PSH 4/1 along with your stroke, load and accuracy requirements to your inquiry list, and we'll help confirm the selection and reply with the factory quote and lead time.
