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 5 V pulse, which toggles the flipper position. The rear face of the unit features an array of vent holes to aid cooling. A TPS001 universal power supply is included with the unit, as is a location-specific adapter.

A remote handset (MFFHS1) is available for use with the MFF001. This small (40 mm x 40 mm x 20 mm) unit is powered by a 3 V lithium battery and shipped with a 2 m long cable. The cable can be extended up to 3 m using a standard SMA to SMA cable. To comply with EMC regulations, the total cable length should be no longer than 3 m.

The mount is supplied complete with our LMR1 (/M) Ø1" 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. The flipper mount is ideal for many optics, including mirrors. When used with a mirror, please note that the MFF001 is not recommended for applications requiring better than 100 µrad beam stability.

Please note that optics in excess of 1.5" (38.0 mm) diameter will affect 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 parentheses.

Could you tell me the mechanical precision of the MFF01? the variability of the angle of the content? e.g. if I put a mirror in it, how much pointing precision I can expect?

Response from Sean at Thorlabs: Thank you for your feedback. Unfortunately, we have not measured the pointing accuracy of the MFF001. We are planning to release a replacement for the MFF001 soon, and based on your feedback we have added the pointing accuracy to the list of specifications we will measure for the new product. I will contact you directly to see if we can offer additional support for the current MFF001.

Response from Tim at Thorlabs: This product uses a TTL logic 5V high pulse trigger via the SMA female. As one example, you could use a DAQ card controlled by your PC for this operation.

A response from Tyler at Thorlabs: I tested one unit of the MFF001 to measure the beam deviation as the mounted mirror was flipped into and out of position. The measurement was made using a BC106-VIS beam profiler that measured the centroid of the reflected beam. The MFF001 should not be used in an application that requires better than 100 micro radian stability in the beam deviation from a beam reflected off a mirror mounted in the MFF001.

A response from Tyler at Thorlabs: The MFF001 could certaily be used to hold a mirror but I don't have a reflected beam deviation specification. I would be happy to get one into the technical support lab and make a measurement that could be used as a guidline for the devices performance as a mirror flip mount.

Would you recommend the device for flipping a mirror in and out of the beam. What is the beam pointing deviation from using it this way?

Hi. Could you give me an update on when the design changes will be ready to integrate position information. Also could you tell me the tolerane on the power supply voltage - could it run from 12V? Thanks

We have committed to using this product in a remotely controlled apparatus and are also concerned about the method of control. It certainly would be better to have remote control of the flipper state (e.g., 5v for up, 0v for down). Also, the output should tell you the current state, not that the stage is flipping. We have asked customer support if there is a known way to modify the existing units.

Response from Javier at Thorlabs to last poster: Thank you very much for your feedback. We will modify the design of the MFF001 in order to integrate position information into the mount. Please contact us at techsupport@thorlabs.com for status updates.

It would be hugely more useful if this device switched to one state at 0v and another at 5v rather than just toggling. I understand it is trivial to make a little circuit to emulate this but without an end-sense for position it is not reliable. Any chance youll offer a modification? I suspect >95% of users would prefer this interface.

A response from Tor at Thorlabs to Ed: Thank you for your interest in our Motorized Mirror Flipper. Our testing shows good repeatability up to the 500-hour mark. We havent tested it beyond that, so we dont have a spec on MTBF. The torque applied to the MFF001 must not exceed 35 N·mm. The MFF001 requires a 15-V, 1-A source -- the recommended after-market supply would be the TPS001: http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1710

do you have an estimated life - number of cycles, MTBF, etc. for this product? would any periodic maintenance be needed to achieve, or exceed, this lifetime? also, id like some more details on the power supply - current requirement and connector specification. thanks -ed

A response from Oli at Thorlabs to t.godden: The MFF001 can indeed take a TTL trigger, any rising edge going above 4.8v will cause it to trigger. The easiest way to achieve this manually is to use the MFFH01 remotely or from the button on the top.

We would like to remotely control the motorized mirror filter flippers MFF001 we recently purchased. I understand it uses a TTl voltage trigger 5V. Could you please recommend/advise me a source for such a trigger. Can we use a standard DC power supply 5V and switch it on and off rapidly and if, so what length of pulse do we need? Many thanks, apologies for my ignorance on TTl!!

Response from Javier at Thorlabs to juergen.bosse: Thank you very much for your feedback. The current design of the MFF001 motorized flipper does not feature a sensor that allows retrieval of the actual position of the flipper. However, you can use the Trigger In/Out connections on the flipper for this purpose. I will discuss a more straightforward way of determining the flippers postion with our design engineers and keep you updated.

Hi there. Do I read the documentation correctly that there is no static indication of the 0deg or 90deg flip position? If a maintenance person, or, worse, the end user is entering our automated environment, we fear that they might "test" the flip mount and might leave it in an unexpected state. Since we have no way of knowing the actual state at boot time of our controller, this would require some extra work. Is there an optional sensor to tell us 0deg or 90deg? Thanks, Juergen.

A response from Adam at Thorlabs to Tom: Tom, I am sorry, but we removed our feedback from 12/28 because it was incorrect. There are permanent magnets used in the motor and the sensor and there is an EMF induced when actuated.

I am considering the MFF001 for an OEM application. I was very disappointed to discover that the dovetail mount on the mirror holder was mounted very far off perpendicular to the mount surfaces (several degrees, visibly misaligned.) It was so far off that I ran out of adjustment range to compensate for it with a 1" kinematic mirror mount. I wasted more than an hour before I realized your mount had been assembled misaligned. I tried to remove and readjust the dovetail, but it tends to rotate when you tighten the screw. (Im sure this was the problem is assembly on your end.) It looks like there is a hole for an alignment pin on the mirror mount, but no mating hole on the dovetail. I think you should improve the design and/or assembly of the mirror mount for this unit so that the mirror is mounted within 0.1 degree of perpendicular. I would like to hear about your plans to resolve this issue as it will determine whether we use your motorized flipper or a product from a competitor in our product. Thanks, Craig
