Introducing two new optical shutter systems from SRS — the
SR470 Laser Shutter Controller and SR474 Four-Channel
Laser Shutter Driver. These shutter systems are designed
specifically to minimize vibration on your optical table.
They are built around a unique shutter head design, supported
by one of two available controller models. The SR470
provides timing signals to a single shutter head, while the
multi-channel SR474 drives up to four shutter heads, and is
controlled by external timing signals.
The Shutter Head
Unlike conventional solenoid based shutters, the SR475
and SR476 shutter heads contain a closed-loop DSP control
system that precisely guides the shutter blade between open
and closed positions, never encountering physical stops.
Vibration and mechanical noise are kept to a minimum,
leaving your optical table disturbance-free.
The shutter blade is mounted between sapphire jewel bearings
that minimize friction and result in a head lifetime in excess
