inside the equipment.
Caution - Risk of danger
This symbol indicates that safe handling and usage
instructions must be followed to avoid injury and/or damage.
DANGER –LASER RADIATION
AVOID EYE OR SKIN EXPOSURE TO DIRECT OF
SCATTERED RADIATION
CLASS 4 LASER PRODUCT
IEC 60825-1:2014-05
Maximum Output: 2W
Emitted Wavelengths: 398nm-643nm
AVOID EXPOSURE –LASER RADIATION IS
EMITTED FROM THIS APERTURE
This symbol indicates that Class 4 laser radiation emits from
the aperture to which this label is closely affixed.
CAUTION –CLASS 4 VISIBLE AND INVISIBLE
LASER RADIATION WHEN OPEN AND INTERLOCKS
DEFEATED. AVOID EYE OR SKIN EXPOSURE TO
DIRECT OR SCATTERED RADIATION.
This label indicates that removal of the panel to which this
label is affixed will permit laser radiation in excess of Class 3B
when interlocks are failed or defeated.
DANGER –OPTIONALLY INTERLOCKED
PROTECTIVE HOUSING PANEL
Visible and/or invisible laser radiation when open
and interlock failed or defeated. Avoid eye or skin
exposure to direct or scattered radiation.
This label indicates that removal of the panel to which this
label is affixed will permit laser radiation in excess of Class 3B
when interlocks are failed or defeated.
See section 6 for locations of each label.

4Introduction and Intended Use
The LDI is a multi-wavelength laser-diode light source intended for use in fluorescence imaging
applications. The LDI is a standalone unit, designed to operate on a desk or bench and connect to a
microscopy instrument or other imaging equipment via optical fibers.
The LDI-6 has six discrete wavelength channels (RGGBBV) while the LDI-7 has seven (RGGBBV + 555nm).
The LDI-6 has one output aperture for all channels and the LDI-7 has two output apertures: one for
RGGBBV channels and another for the 555nm channel. 89 North supplies an optional 400 m bifurcated
fiber to combine the two LDI outputs into one fiber.
Because of its intense brightness, the LDI includes several safety interlocks that, when tripped, will block
the laser emission produced by the system. Do not override these interlocks. Doing so may result in injury
to the user and/or the unit and will immediately void the warranty.
