Current Lead Time: 3 – 4 weeks

Expedites are subject to availability and will be approved upon order confirmation.

The Uniblitz LS3 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 LS3, 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. The 501A-S7 is not included with the purchase of an LS Series Shutter. Additionally, the 5-pin female mating connector (5F) is no longer included with purchase.

Vacuum compatibility option available upon request.
