UHS1 SERIES SHUTTER
SPECIFICATIONS Page 1 of 2
FEATURES
• 1mm diameter aperture
• Fastest shutter in the UNIBLITZ® line of electroprogrammable
shutters.
• 350ìsec total exposure time in the (HIGH) speed
mode.
• 180ìsec rise time.
• Activated by an electronic pulse through
shutter driver module, the DM412, included.
• Exposure repetition rate continuously variable
from DC-400Hz.
• Electronic synchronization system included.
• Non-resonant design allows instantaneous changes
in repetition rate and duty cycle in the normal
(NORM) mode.
• 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 350ìsec! 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 VCM/VMM type 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 VCM/
VMM type 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. See page #2
(Figure 3) for DM412 panel layout drawings.

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.
