LS2 2mm Laser Shutter
$670.00 – $1,265.00
Current Lead Time: 5 – 6 weeks
Current Lead Time: 5 – 6 weeks
The Uniblitz LS2 is a high-performance laser shutter, ideal for precision exposure control, laser switching, and other applications that benefit from the precise, repeatable characteristics of the LS shutter series. These include low level laser chopping, and pulse gating, selection, and modulation to 400Hz.
Uni-stable shutter devices, like the LS2, require power to hold the blades in the open state (though the device can be custom-configured for “normally open” operation).
A 501A-S7 Shutter Adapter Cable is required for use with VMM-D3, VMM-D4, D880C and any VCM-D1 purchased prior to November 2022.
Vacuum compatibility option available upon request.
- 2mm aperture
- Uni-stable operation
- Laser Energy Rating: 5 W/mm2 (with “ZM” blades)
- RoHS Compliant
- Transfer time on opening: 0.3 milliseconds
- Total opening time: 1.0 milliseconds
- Configured for the VCM-D1 Shutter Driver
For additional technical information please see the LS2 Laser Shutter Datasheet.

1 Voltage level required across actuator coil when being held in the open position.
2 (Continuous/Burst) Continuous frequency rating specified at shutter’s minimum exposure pulse. Burst frequency rating specified for four (4) seconds maximum with one (1) minute minimum between bursts.
Electronic Synchronization System
The Electronic synchronization system provides a feedback signal (through the driver utilized) after the shutter transfers to the open state. The system incorporates an infrared emitting diode, an infrared sensitive detecting transistor, and an interrupting vane. The vane is attached to the shutter so as to block the light path between the emitter and detector in the closed position. When the shutter transfers to the 80% open position, the vane is removed from the infrared light path, allowing the emitter to switch the detector to the active state. For the LS2, this system uses a similar activation flag attached to the mechanism, which triggers a reflective emitter/detector device. No connection to the designated synchronization pins when no electronic sync. is selected.
The question regarding enhancement of shutter speed with the application of user supplied lubricants has been repeatedly asked. It is our experience that lubricating the shutter blades will actually slow the shutter down and eventually render the shutter inoperable. Under no circumstances should any type of lubricant be applied to the shutter blade area.
