Melles Griot manufactures state of the art electronic shutters for laboratory and OEM applications. Our IES™-series shutters include an adjustable iris diaphragm, X synchronization, and a "manual actuation" lever that allows the shutter to operate without an electrical signal. Our UltraThin™-series shutters are designed to fit into restricted spaces. In both series, Spring-steel blades with a Teflon-impregnated, black matte finish, coupled with a reliable, multiblade shutter mechanism guarantee high operational speed and near 100% light extinction as well as smooth and dependable operation. Normally closed and normally open blade configurations are available. Rated nominal voltages for standard solenoids are 3-,6-,12-, 24-, and 48-Vdc. Controllers are available for standard 12-V shutters, and our 12-V shutters include a mating cable.

The powerful wireless components from elero can also overcome complex control tasks: whether wireless retro-fitting of existing drives, control of roller shutters or sun protection via venetian blind switches or integrated light control.
Innovative products offer installers the possibility to optimise the advantages of using wireless technology for every installation site, and develop individual radio solution from this.

One of the most popular features on our newest Phantom cameras is an
internal mechanical shutter. It is used to automatically shade the sensor
during a Current Session Reference (CSR). This allows the camera operator to
do a CSR without manually capping the lens.
Because of the overwhelming popularity of this feature, we’ve decided to bring
it to our existing line of V-Series cameras – the v5.2, v7.3, v9.1 and v10.
Everything you need to upgrade your camera and software is included in
the V-Series Lens Shutter Kit: VRI-EXTSHUTTER-F-MOUNT. Or, if you want
Vision Research to do the camera upgrade for you, order VRI-EXTSHUTTER-
F-MOUNT-UPG, and return the camera to us. To have the shutter added to a new camera order, specify the option VRI-EXTSHUTTER-F-MOUNT-OPT.

Many applications in new and old buildings with compact design
The folding shutter is in vogue. Both in old and new buildings, we often choose a conventional and classic solution with a modern design. This solution supports safety, saves energy and is used as a solar protection system.

elero controls offer you a lot of advantages:
More comfort - your sun protection systems are operated easily by the press of a button.
More safety - roller shutters which are controlled by timers protect against thiefs and burglars.
Easy operation - fully automatic control by radio or press of a button.
Low energy consumption - prevent the undesirable drop in room temperature through automated roller shutters.
Low installation effort - easy installation of the control units without dirt and noise.

Jacobsen's x-ray beam shutter is an add-on component for x-ray systems.
The shutter enhances machine safety and extends x-ray tube life and can be integrated into an existing x-ray system.
Installing a shutter allows x-rays to remain on during product loading, helping to reduce cycling of the x-ray tube, and in turn increasing x-ray tube life.
