Vincent Associates prides itself on the quality bi-stable shutters manufactured available for use in numerous applications including but not limited to video imaging, telescopy, microscopy, holography, and x-ray switching.
Bi-stable shutters are devices that do not require power to hold them in the open or closed state. These devices only require power when switching from one state to the other. There is no default state. The shutter will remain always in the last state to which it was switched. A bi stable shutter works best in applications where power is at a premium or when heat emitted from the shutter's actuator during the time it is being held in the open (or active state) is a concern as it could be within a vacuum.
The NS and DSS series are designed to be bi-stable in nature. These usually require less power to switch them and can, in some cases, as with the new DSS series, operate as low as +5VDC. We also have a BDS25 device that is a bi-stable version of the CS25. The BDS25 is not a standard product, however, it is available upon request. Larger CS apertures can also be manufactured bi-stable upon request.
Vincent Associates has a number of apertures and bi-stable shutter types available to meet most applications. Shown below is a quick comparison of the available bi-stable shutter types and some of their features.
If you cannot locate a device that will work within your application please check out our custom capabilities or contact us today for further assistance.
