These Two-Position, High-Speed Flip Mounts flip lenses, filters, and other optical components into and out of a free-space beam. As shown by the image below, up to two optic mounts can be attached to the same flipper unit, allowing the user to alternate between optics. The flip action can be controlled in four ways: by the button on the top of the unit, via the included remote handset, via the external SMA connectors, or via a PC running the included APT software (see the Motion Control Software and APT Tutorials tabs for more information). The flipper position rotates 90° clockwise or counterclockwise when it is toggled and may be toggled either by an absolute signal level (i.e., low and high control voltages correspond to specific flipper positions) or by an edge (i.e., a change in the control voltage level causes the flipper to rotate). The unit has magnetic limit switches at both positions to identify which position the flipper is in.

The flipper units offer a compact 30 mm x 30 mm cross section and have two SMA connectors on the side face, marked DIG I/O 1 and DIG I/O 2, which accept input signals from the remote handset or from an external trigger. They can also be configured by a PC running the included APT software to output signals when "In Motion" or "At Position." Software settings can be saved (persisted) within the unit to enable use without a PC.
The MFF101(/M) comes with an LMR1(/M) Ø1" optic mount, which holds an optic with the included SM1RR retaining ring, while the MFF102(/M) comes with an LMR2(/M) Ø2" optic mount, which holds an optic with the included SM2RR retaining ring. Any of our other mounts from the LMR Series or FMP Series can be attached to the flipper mount, so long as their optic diameter does not exceed 2.0" (50.8 mm). As shown in the image above, a bracket connects the optic mount to the flipper unit. The optic mount is held to the bracket by an 8-32 (M4) screw, and the bracket is held to the flipper unit by a flexure clamp. The flexure clamp tightens using two setscrews that accept the provided 0.035" (0.9 mm) hex key. Two brackets and two 8-32 (M4) screws are provided with each flipper unit.
A bottom-located 8-32 (M4) tapped hole allows the flipper to be mounted on a Ø1/2" post. The flipper is powered by the included 15 V power supply, which ships with a location-specific plug. A 1.5 m (59") long micro-USB to USB cable is also included to connect the flipper to a PC for control and configuration.
The flipper is ideal for use with many types of 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. The torque applied to the unit should not exceed 0.1 N•m, and the maximum load capacity, including optic mounts and optics, is 120 g (4.23 oz). The side face of the unit contains an array of vent holes to aid cooling; please ensure that the air flow around these vent holes is not restricted.

Thorlabs offers two platforms to drive our wide range of motion controllers: our Kinesis® software package or the legacy APT™ (Advanced Positioning Technology) software package. Either package can be used to control devices in the Kinesis family, which covers a wide range of motion controllers ranging from small, low-powered, single-channel drivers (such as the K-Cubes™ and T-Cubes™) to high-power, multi-channel, modular 19" rack nanopositioning systems (the APT Rack System).
The Kinesis Software features .NET controls which can be used by 3rd party developers working in the latest C#, Visual Basic, LabVIEW™, or any .NET compatible languages to create custom applications. Low-level DLL libraries are included for applications not expected to use the .NET framework. A Central Sequence Manager supports integration and synchronization of all Thorlabs motion control hardware.

APT GUI Screen
Our legacy APT System Software platform offers ActiveX-based controls which can be used by 3rd party developers working on C#, Visual Basic, LabVIEW™, or any Active-X compatible languages to create custom applications and includes a simulator mode to assist in developing custom applications without requiring hardware.
By providing these common software platforms, Thorlabs has ensured that users can easily mix and match any of the Kinesis and APT controllers in a single application, while only having to learn a single set of software tools. In this way, it is perfectly feasible to combine any of the controllers from single-axis to multi-axis systems and control all from a single, PC-based unified software interface.
The software packages allow two methods of usage: graphical user interface (GUI) utilities for direct interaction with and control of the controllers 'out of the box', and a set of programming interfaces that allow custom-integrated positioning and alignment solutions to be easily programmed in the development language of choice.
A range of video tutorials is available to help explain our APT system software. These tutorials provide an overview of the software and the APT Config utility. Additionally, a tutorial video is available to explain how to select simulator mode within the software, which allows the user to experiment with the software without a controller connected. Please select the APT Tutorials tab above to view these videos.
The APT video tutorials available here fall into two main groups - one group covers using the supplied APT utilities and the second group covers programming the APT System using a selection of different programming environments.
Disclaimer: The videos below were originally produced in Adobe Flash. Following the discontinuation of Flash after 2020, these tutorials were re-recorded for future use. The Flash Player controls still appear in the bottom of each video, but they are not functional.
Every APT controller is supplied with the utilities APTUser and APTConfig. APTUser provides a quick and easy way of interacting with the APT control hardware using intuitive graphical control panels. APTConfig is an 'off-line' utility that allows various system wide settings to be made such as pre-selecting mechanical stage types and associating them with specific motion controllers.
APT User Utility
The first video below gives an overview of using the APTUser Utility. The OptoDriver single channel controller products can be operated via their front panel controls in the absence of a control PC. The stored settings relating to the operation of these front panel controls can be changed using the APTUser utility. The second video illustrates this process.
APT Config Utility
There are various APT system-wide settings that can be made using the APT Config utility, including setting up a simulated hardware configuration and associating mechanical stages with specific motor drive channels. The first video presents a brief overview of the APT Config application. More details on creating a simulated hardware configuration and making stage associations are present in the next two videos.
The APT Software System is implemented as a collection of ActiveX Controls. ActiveX Controls are language-independant software modules that provide both a graphical user interface and a programming interface. There is an ActiveX Control type for each type of hardware unit, e.g. a Motor ActiveX Control covers operation with any type of APT motor controller (DC or stepper). Many Windows software development environments and languages directly support ActiveX Controls, and, once such a Control is embedded into a custom application, all of the functionality it contains is immediately available to the application for automated operation. The videos below illustrate the basics of using the APT ActiveX Controls with LabVIEW, Visual Basic, and Visual C++. Note that many other languages support ActiveX including LabWindows CVI, C++ Builder, VB.NET, C#.NET, Office VBA, Matlab, HPVEE etc. Although these environments are not covered specifically by the tutorial videos, many of the ideas shown will still be relevant to using these other languages.
Part 1 illustrates how to get an APT ActiveX Control running within Visual Basic, and Part 2 goes on to show how to program a custom positioning sequence.
Full Active support is provided by LabVIEW and the series of tutorial videos below illustrate the basic building blocks in creating a custom APT motion control sequence. We start by showing how to call up the Thorlabs-supplied online help during software development. Part 2 illustrates how to create an APT ActiveX Control. ActiveX Controls provide both Methods (i.e. Functions) and Properties (i.e. Value Settings). Parts 3 and 4 show how to create and wire up both the methods and properties exposed by an ActiveX Control. Finally, in Part 5, we pull everything together and show a completed LabVIEW example program that demonstrates a custom move sequence.
