System Overview

Power Connections

Power connections for the High Power Laser Engine and the BCU are identified in the diagrams provided in Rear Panel and Rear panel of the BCU.

As shown below, the BCU is connected via the PS-11 and the High Power Laser Engine is connected from the mains slot via the IEC 60320 C14. The PS-13 is also connected to the 12 V DC inlet when the optional HLE-FL1 laser is present on the HLE.

Please see Electrical Power Specifications, External Power Supply Specifications and Power Supply Information for further information.

Optical Connections

System overviews are provided below for both a single and dual HLE-700 system set up. A system overview is provided below for a typical triple output HLE connected to a Mosaic, Micropoint and Dragonfly (via the BCU) in Figure 15. A typical system overview for a dual HLE-700 is provided in Figure 16. For models with multiple output couplers Mosaic is always connected to the top output coupler. If the HLE contains a single output coupler this connects to the BCU.

Interlock Connections

A BNC connector is provided so that the user can interlock the High Power Laser Engine lasers using external switches or sensors present on microscopes, doors, etc. The contacts must be shorted for the lasers to operate. When the interlock contacts are open, the primary shutter closes, and all the lasers are disabled. The system is sold with a Class 4 Laser-Lock that has two types of interlock inputs: 1) standard interlock for microscope components and 2) remote interlock, typically for the lab door.

The output of the Laser-Lock is connected to a BNC interlock input on the back of the High Power Laser Engine. The contacts on both inputs must be shorted for the lasers to operate.

When the interlock contacts are open, the primary shutter closes, and all the lasers are disabled.

  1. When the microscope interlock is opened, the user must close the interlock and the laser configuration will be re-established.

  2. When the remote interlock is opened the user must close the interlock and then push the button on the Laser-Lock.
