Tunable optical filter
Thorlabs

This two position high-speed flipper has been designed to flip a lens, filter, or other optical component into and out of a free-space beam. The unit is designed to be mounted on a standard M4 or #8-32 post.

The flip action is controlled by a button on the top of the unit. The flipper position toggles 90° between vertical and perpendicular with each button press. The unit has two SMA connectors, marked TRIG IN and TRIG OUT, for use in applications requiring an external or remote trigger. The trigger is a TTL logic high going 5V pulse, which toggles the flipper position.

A remote handset (MFFHS1) is available for use in such applications. This small (40 x 40 x 20 mm) unit is powered by a 3V lithium battery, and is shipped with 2 m of cable. The cable can be extended up to 3m using a standard SMA to SMA cable. To comply with EMC regulations, the total cable length should be no longer than 3m.

The mount is supplied complete with our LMR1 (/M) 1" optics mount, but is compatible with holders in the LMR range up to 1.5" (38.0 mm) diameter as detailed below. Screws are supplied for both imperial and metric lens holders.

Please note that optics in excess of 1.5" (38.0 mm) diameter will effect the functionality of the flipper due to increased inertia. The maximum torque applied to the unit must not exceed 35 N·mm. The table below details the maximum combined weight of the optic and the associated optic holder. The maximum weight of the optic alone is in brackets.
