Ce:YAG + Laser Diode Optical Head (OBSOLETE)
Ce:YAG + LD Fiber Light Source combines the light emissions of a Ce:YAG module and selected laser diode module. It comes with integrated cooling system and respective drivers. This light source is optimized for 200 µm core diameter optical fibers with 0.53 numerical aperture but can be used with other optical fibers as long as they have FC type connector. The fiber-coupled output power increases with the core diameter up to about 600 µm.
Light sources can be controlled manually or using a computer via a USB port and Doric Neuroscience Studio Software. Both channels are controlled independently through software defined sequences or using the BNC input connector of each channel for an external control by analog or TTL signals. Each channel also includes a BNC connector that outputs a voltage proportional to the driving current. This output signal can be used for the synchronization of other devices. Doric Ce:YAG Drivers safety features include a rear panel interlock connector, a master key switch and, for each channel, a white LED illuminated knob indicating if the corresponding source is activated. Unlike most commercial drivers, Doric driving electronics eliminates the leakage current and the corresponding light output when the current is set to zero. This is of crucial importance for optogenetics experiments.
Its optical output is ideal for optogenetics experiments where activation and silencing of opsin labeled neurons is required, for Optogenetically Synchronized Fluorescence Microscopy Systems and for 2-color Fluorescence Microscope Systems.Notes:
- Ce:YAG + LD optical head requires associated Ce:YAG + Laser Diode driver to driver current to laser diodes that generate fluorescence light.
- Each Ce:YAG+ LD optical head comes with an empty Filter Holder for Ce:YAG Fiber Light Source (YFH).
- Different Bandpass filters for Ce:YAG Fiber Light Sources (YBPF) are available.
