Additional information
Download PC control software for QCLDD-2.
Either 14-pin DIL mount, or 14-pin butterfly mount is included with the controller. If purchased together, this controller will be shipped preconfigured for operating with laser diode, superluminescent diode, or semiconductor optical amplifier as a complete turn-key system.
In the butterfly mount option, type I, type II, and a custom routing board are included. The custom routing board allows the user to wire a user-defined pin-out assignment. To change routing boards first disconnect the power supply from the QCLDD-2, remove the back plate of the QCLDD-2, and carefully pull out the routing board applying an even pull on both sides of the board. Then align the desired routing board with the QCLDD-2 sockets, confirm that the arrows marked OUTSIDE are pointing to the outer side of the QCLDD-2, and gently push the routing board all the way down. Re-assemble the back plate.
The QCLDD-2 also includes the AC-DC power supply adapter, the USB cable, and the software control application.
