0. Introduction Thank you for purchasing this FJORD light source from Pyroistech.SL. This document describes the FJORD light source and provides you with instructions for its correct operation. Please do not hesitate to contact us through [email protected] if you have any questions or doubts about this manual. FJORD is the superluminescent diode (SLED) broadband light source that allows you to combine up to 8 high power SLED, with peak wavelengths that range from 830 nm to 1650 nm. Its compact, silent and sturdy design permits its integration in whatever type of application, covering a wide...

Optical characteristics The available SLED for configuring your own FJORD source are the following: Power Density (dBm/nm) The central wavelength of each SLED is included in its own name. For example, SLED HP1130 has a central wavelength of 1130 nm. The power measurements shown in the graph correspond to each individual SLED. The assembly of several SLED modules implies some power losses. Final power measurements will be provided for each FJORD SLED light source separately at the time of assembly. Right now, we have available the FJORD configuration tool, that allows you to combine up to 8 SLED...

2. Operation 2.1 Package Content • Requested FJORD light source • Power source • Power cord • User’s manual Inspect carefully the devices and make sure there is no damage. On the contrary, do not employ the light source and please contact us through [email protected] for repair or replacement information. 2.2 Basic operation Insert the plug of the power cord into the power supply and connect the power cord to the power outlet. Then, introduce the plug of the power supply into the light source power input (DC female type). Unscrew the cap of the FC-PC/FC-APC connector on the front face of the...

Initial screen  General ON/OFF button (1) • If all the SLEDs are OFF, the general ON/OFF button will be OFF (grey). By pressing it, the general button changes to the ON state (light green) and all the SLEDs will be turned ON with the 100% of its power. • If one or more SLEDs are ON, whatever the output power, the general ON/OFF button will be ON (light green). By pressing it, the general button changes to the OFF state (grey) and all the SLEDs will be turned OFF....

SLED ON/OFF button SLED information Spectrum view button Return arrow Figure 2. SLED screen  SLED information (1) On the left of the screen, the following information can be read: • Name of the SLED • SLED Temperature (ºC) • Central wavelength of the SLED • SLED Current (mA) • Full width at half maximum (FWHM) • Type of error (only when an error has occurred, see Figure 5 on next page)  Control of the output power On the right of the screen, the percentage of the nominal output power of the SLED can be adjusted from 0% to 100% with the following controls: • SLED ON/OFF button (2): – This button...

The y axis is the output power of the SLED in arbitrary units in logarithmic scale, where 1 corresponds to the maximum. The x axis is the wavelength in nm. By pressing the arrow on the bottom left corner, you will be returned to the SLED screen (see Figure 2 on p.10). Figure 4. Spectrum view screen 2.5.3 Error management When an error takes place, the user is automatically returned to the initial screen. The SLED where the error has occurred can be quickly identified by looking to the status circle of each SLED and observing which one is red. There will also be a warning symbol in the rectangle...

2.6 USB connection (available extra) The aim of the USB connection is to allow the user to control the output power of each SLED and monitor its temperature through the computer. This option permits to remotely command the source through a VPN connection, for instance; avoiding the inconvenience of physically going to the laboratory to check or adjust the equipment. An app is provided (contact us through [email protected] for more information) and commands can also be directly sent to the source to check and modify additional variables. Both are explained in detail in the following pages. 2.6.1...

2.6.2 App: Control and monitoring Once the connection has been made, the drop-down menu that allows you to choose the desired SLED and the widgets that let you control the output power will be active. The connection between the computer and the FJORD light source can be closed at any time by clicking on “Disconnect” (5). • In the drop-down menu (6) we can select each SLED that is in the light source. • For the selected SLED, the temperature in ºC is shown (7). This value is updated every second. • The output power of the selected SLED can be varied from 0 to 100 % by using the slide bar (8) or...
