2.2 Overview of the
⋆
LISER
TM
& LED/LD Light Source
The Doric
⋆
LISER
TM
& LED Light Source includes a LED light source combined with the
⋆
LISER
TM
source (Fig. 2.2 ). The
light from both sources are mixed using an optical combiner. The
⋆
LISER
TM
& LED/LD Light Source is considered as a
Class 3B laser product. It is critical to follow the safety instructions stated in this manual. The device has the following
elements.

LISER
TM
& LED/LD Fiber Light Source
• The Beam Aperture is where the light exits the light source. The aperture is composed of a fiber coupling
assembly that injects the emitted light into an optical fiber. The standard model uses an FC fiber connector. A
safety FC metal cap is attached to the optical head to block the output light beam in absence of optical fiber.
• The Fan Grids are found on the top, rear and side of the light source. They must be kept clear at all times to
avoid overheating the system.
• The Removable Filter Holder is used to insert an optical bandpass filter in the system, allowing the selection of
a narrow part of the broad Ce:YAG spectrum of emission. The filter holder can accept any filter up to a 25.4 mm
diameter and a maximum 5 mm thickness.
• The BNC LISER Input Port is used to command the
⋆
LISER
TM
source.
• The BNC LED Input Port is used to command the LED/LD source.
• The BNC LISER Output Port is used to monitor the
⋆
LISER
TM
source.
• The BNC LED Output Port is used to monitor the LED/LD source.
• The Power On/Off switch turns on/off the driver.
• The Key Switch must be in place to enable light emission. Note that, despite its similar form factor, the power
key is not a standard micro SD card such as those used in some digital cameras. Do not attach the Key to a key
fob or similar holder; this may prevent proper insertion of the Key Switch .
• The 12 V port connects the
⋆
LISER
TM
to its 12 VDC power supply.
• The USB port allows the user to connect the
⋆
LISER
TM
to a computer using a USB-A/USB-B cable. This allows
the driver to be controlled using Doric Neuroscience Studio .
• The Interlock connector plug allows the user to connect the
⋆
LISER
TM
to a safety interlock system. It is recom-
mended to connect the interlock plug to a laboratory interlock system (See chapter 1 ).
