Important Operating Guidelines
- DO NOT INSERT A MIRROR INTO THE SOCKET UNTIL STEP 5 OF THE MANUAL.
- Never exceed the specified maximum voltage level and angles specified for each delivered
mirror on an individual datasheet enclosed with your development kit.
- Always perform tests that include any new settings such as new drawings, new refresh rates,
new filter settings etc, at LOW voltage settings until you can verify that those settings are
working properly and not exciting the device beyond mechanical limits (usually -6° to +6°,)
or beyond voltage limits.
- The devices are sensitive to electrostatic discharge; always insure adequate grounding when
handling the chips. A wrist grounding strap with a 10MΩ series resistance is recommended.
- Many of the devices have anti-reflection (AR) coated windows that should not be directly
handled. Any handling of the micromirror chip should be done with care to maintain the
AR-coated window as clean as possible. The window can be cleaned with isopropyl alcohol
and light rubbing with fine lens-cleaning cloth.
- Some devices may be shipped without AR-coated windows, for better performance with
customer-specific lasers, etc. Those devices are most fragile due to the exposed MEMS
structures and should be handled with extra care and never touched with any object to the
device area, including streams of blowing air and similar disturbances.
- Do not plug-in or un-plug any cables of the USB MEMS Controller while the micromirror
is connected to the HV amplifier. Please lower voltage settings, disable the amplifier and
set the switch on the micromirror MiniPCB to the OFF position.

STEP 2: DO NOT INSERT A MIRROR INTO THE ZIF UNTIL STEP 5. Plug the USB cable into your PC and
the USB-SL MEMS Controller. Your PC will automatically detect and install the device. If the drivers are not
installed automatically, install the drivers under the following directory for your specific USB MEMS Controller
card version: C:\MirrorcleTech \Drivers.
STEP 3: Mirrorcle Software Installation. Insert the software installation CD from Mirrorcle Technologies, and
follow the instructions provided in the README file.
STEP 4: Assemble the optical hardware. If required configure the laser mount, static mirror mount and
micromirror mount as shown in the following figures.

STEP 5: For the 24-pin holder the ZIF lever indicates the bottom of the socket (opposite a “normal” ZIF
configuration.) On the micromirror chip the notch indicates the top of the chip and the gold square denotes pin
#1. Take care not to touch the protective glass covering the micromirror device. See figures below for more
details. For the LCC18 socket, please refer to the LCC Device Handling document.
CAUTION: The micromirror chips are sensitive to electrostatic discharge, insure that you are well grounded
prior to removing the chip from its package and while inserting the chip into the socket. Also, when inserting
the chip take extra care to insure the pins are aligned and not bent during the insertion processes.
Prior to inserting the device into the ZIF socket, then raise the lever on the ZIF socket to the up position (90º to
MiniPCB.) Carefully insert the micromirror DIP into the ZIF socket and gently lower the ZIF lever to the down
position (CAUTION: do not allow the lever to snap down!)
Note: MiniPCBs 5.0 and newer do not have the ON/OFF switch. When handling devices, disable the MEMS
driver or unplug the HVOut cable from the USB MEMS Controller.

CAUTION: Prior to connecting the HV amplifier to the micromirror MiniPCB make sure that the switch on the
micromirror MiniPCB is in the OFF position.

STEP 6: Connect the free end of the MEMS driver 10-pin ribbon cable, colored in RED, to the micromirror
MiniPCB. Connector‟s plastic shroud should ensure proper pin alignment. The cable is colored on one end
simply for user‟s convenience of identifying various cables, however both 10-pin cables and both ends are
interchangeable.
STEP 7: Start the software “MirrorcleDraw” from the Mirrorcle folder of your computer‟s Programs menu. In
the software‟s graphical user interface (GUI) ensure that the output device is selected to be the proper USB
MEMS controller card (e.g. if multiple controllers are plugged into the PC, user should select the desired output
controller). Set the “Max Voltage” to approximately 80V or a similar „safe‟ value that is lower than the
maximum voltage number specified in the MEMS mirror‟s datasheet.
Warning: The maximum voltage value should be less than or equal to the maximum allowed voltage
published with the specific device‟s datasheet (page 1). Values higher than maximum allowed for a
specific device can cause erroneous behavior or device damage.
STEP 8: After all of the connections are made and with the MEMS driver still off (“Enable Amp” in
MirrorcleDraw GUI is still unchecked and red LED “HV On” on Controller‟s front panel is off), set the switch
on the micromirror MiniPCB to the ON position.
STEP 9: Select “Vector Graphics” as the Program Mode, and it defaults into “Waveforms” Function.
Warning: The filter cut-off frequency should not significantly exceed the recommended filter
published with the specific device‟s datasheet. Values significantly higher than the recommended filter
value can cause ringing, larger angle overshoot, and device damage.
Click on “Enable Amp” on the GUI. The red LED on the amplifier box should be ON now.
Turning Off the Kit Safely
Do not plug-in or un-plug any cables of the USB MEMS Controller while the MEMS mirror is
connected to the HV amplifier. Please lower voltage settings, disable the amplifier checkbox in the
GUI (EnableAmp) and set the switch on the micromirror MiniPCB (if present) to the OFF position.

Appendix 1: Replacing the Micromirror Device Chip
1. In software, reduce voltage setting to minimum
and turn OFF Enable Amp checkbox. Confirm that
the X and Y voltages are close to zero. Always
wear clean lab gloves and observe electrostatic
discharge (ESD) protection procedures when
handling devices.
3. Carefully remove the package from the ZIF,
taking care to hold it only on the package sides, not
in any areas near the device cavity and the device
itself. It might be helpful to slightly put fingers
behind the package to ensure a firm hold.
2. While holding the package against the MiniPCB,
(to prevent it from falling out when the ZIF lever is
released), slowly release the package by moving the
lever on the ZIF package to the open position using
two fingers
4. Store the device in a static-free and secure
environment, e.g. antistatic foam boxes.
Replace the package by the reverse process, again taking care not to touch the micromirror die
within the package cavity, or wire bond area. Insert the package into the ZIF socket and hold it
flush against the ZIF by using two fingers. Capture the package in the ZIF by closing the lever
slowly. Do not allow the ZIF lever to snap using spring force – the shock may damage the device –
always use fingers to control its position.

Appendix 2: The Amplifier
USB-SL M4 MEMS Controller with Embedded MEMS Driver
Amplifier is embedded with the USB-SL MEMS Controller card. Amplifier does not require external power
supplies since +5VDC is provided from the USB input to the controller (back panel, labeled USB). The biased
differential high voltage analog outputs are provided by the controller via the 10-pin ribbon cable under the label
MEMS. Mirrorcle‟s APIs and executable software allows the user to use 8 digital channels for synchronous
triggering of lasers, cameras, etc under the label Digital. The USB MEMS Controller also has two analog inputs,
available to be connected on the front panel under the label Analog. Mirrorcle Software and API further allows
the user to trigger the USB MEMS Controller externally, or provide a trigger to additional MEMS controllers.
This synchronization trigger is available on the port under the label Sync. The front panel has two LEDs: a
green LED to indicate the controller has +5V On, and a red LED to indicate the amplifier‟s HV On (MEMS
driver) status.
