• 1mm diameter aperture
• Fastest shutter in the UNIBLITZ®line of electro-
programmable shutters.
• 300µsec. total exposure time in the (HIGH) speed
mo de.
• 100µsec. rise time.
• Activated by an electronic pulse through shutter
driver module, the DM412, included.
• Exposure repetition rate continuously variable
from DC-400Hz.
• Non-resonant design allows instantaneous changes in
repetition rate and duty cycle in the normal (NORM)
mo de.
• No optical surface when open provides 100%
transmittance
The UHS1 supersedes the LS2 as the fastest shutter in
Vincent’s UNIBLITZ line. As with the LS series, the
UHS1 is specially suited for laser use, with applications
including low level chopping, high speed switching, pulse
gating and selection, and modulation to 400 Hz. In the
high speed mode (HIGH) the UHS1 produces a total
exposure pulse of 300µsec! This speed is
unprecedented in Vincent type instrumentation shutters.
In the normal speed mode (NORM) the shutter is
programmable, and activated by an electronic pulse
generated by Vincent’s drive module, the DM412. This
module is included with the UHS1, and will interface with
the D122 and T132 controllers. The DM412 converts the
specialized shutter drive outputs into the voltage pulses
necessary for proper operation of the UHS1.
DM412 Drive Module:
Operation of the DM412 is simple and straightforward. All
activate functions are supplied through the D122 or T132
shutter drivers. The only controls integral to the DM412
are the NORM/HIGH switch which allows “on the fly”
selections between the normal (NORM) and high (HIGH)
speed modes. The CONTROL BNC allows TTL (active
low) or remote switch (710R) to electronically select the
normal and high speed modes, providing greater
flexibility.

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.
