Introduction
These two position high speed flippers have been designed to flip a lens, filter or other
optical component into and out of an open beam.
The flip action is controlled by a button on the top of the unit, via the remote handset
included, or via a control PC. The flipper position toggles 90° between vertical and
perpendicular with each button press. The unit has two SMA connectors, marked
DIG I/O 1 and DIG I/O 2, for use in applications requiring an external or remote trigger,
e.g the remote handset. The trigger is a button press or a TTL logic pulse, which
toggles the flipper position. The rear face of the unit features an array of vent holes to
aid cooling.
This small (70 mm x 30 mm x 30 mm) unit is powered by the included 15V power
supply. It is shipped with a 1.5 m (59.0”) USB cable.
The MFF101(/M) is supplied complete with our LMR1 (/M) Ø1" optics mount, while the
MFF102 is shipped with the LMR2(/M). Other holders in the LMR range are
compatible, up to a maximum diameter of 50.8 mm (2”). The flipper mount is ideal for
many optics, including mirrors. When used with a mirror, please note that the unit is
not recommended for applications requiring better than 100 µrad beam stability.
