The HL-2000 is adjusted at the factory to provide maximum power into a 200µm fiber. If a lower optical power is required or a different fiber (bundle) diameter is used, you can adjust the optical power of the unit. Refer to HL-2000 Diagrams while using the following procedure.
► Procedure Follow the steps below to adjust the optical power of the HL-2000 Light Source:
1. Connect a fiber optic spectrometer or an optical power meter to a fiber, and then connect the other end of the fiber to the HL-2000’s SMA plug.
2. Loosen the blocking screw with the provided 1.3mm Allen wrench.
3. Shift the SMA socket to optimize the optical power of the HL-2000.
4. Tighten the blocking screw to secure the SMA socket position.
Identifying the Bulb Type
► Procedure
Perform the steps below to identify the bulb type:
1. Unplug the power connector from the power socket on the HL-2000.
2. Loosen the screws on the rear of the unit with the provided 2.5mm Allen wrench.
3. Remove the backside of the HL-2000 and remove the electronics board from the HL-2000, taking particular care not to disconnect the fan wires.
4. Remove the screws from the bottom plate of the unit with the provided 1.3mm Allen key.
Replacing the Bulb
► Procedure
Refer to Figure 5 and perform the steps below to replace the bulb in the HL-2000 Light Source:
1. Unplug the power connector from the power socket on the HL-2000.
2. Loosen the screws on the rear of the unit with the provided 2.5mm Allen wrench.
3. Remove the backside of the HL-2000 and remove the electronics board from the HL-2000, taking particular care not to disconnect the fan wires.
