SEE HOW IT WORKS!

TiNi’s Optical Shutter was first developed for SWRi (South West Research Institute) for the New Horizons mission to Pluto. It provides a simple and effective means to let light into sensitive instruments. The aperture cover is opened on command and may be manually reset to support ground testing.

TINI OPTICAL SHUTTER OFFERS THE FOLLOWING ADVANTAGES:

NEA (Non-Explosive Actuators) – 
As with all TiNi products, the Shutter is non-pyrotechnic and field reset-able with a minimum qualified life of 100 cycles.

Field Reset-able and Reliable – 
The Shutter is reset by simply re-cocking the gate that is used to cover the aperture.  This is accessed from the side of the Actuator and may be operated with a simple tool provided.

Redundant Firing Circuit – As with all TiNi Actuators a redundant SMA circuit is incorporated. This provides complete electrical redundancy as well as mechanical redundancy for the critical TiNi trigger element.

Fast Acting – 
By directly passing current through the SMA element, TiNi Shutters perform in millisecond time frame making them ideal for time sensitive applications that also require low power consumption.

Auto Shut-Off Switches – 
Simple Auto Shut Off Switches are incorporated into each Shutter to protect the TiNi Trigger.  This makes them very “user friendly” and operable from a wide range of current and voltages.
