3.3.2 Installation of Laser System and Adjustment of Fiber Coupler
Please follow the instructions given in each of the user’s manuals to install the laser
system and fiber coupler, and make adjustments so that the connection between the
laser source and fiber coupler can be optimized.
WARNING
You should strictly follow the laser hazard class 3B safety requirements whenever
you install, adjust, or remove the fiber coupler from the laser system, and connect or
disconnect the fiber from the CSU-X1.
Never touch the tip of the fiber and be most careful to keep the fiber tip clean. If you
touch or damage the tip, the laser output power at the fiber will be affected, and
thus the confocal image will be impaired. When you measure the laser output power
at the fiber tip, please set the laser power at the minimum level. Possibility of
damage to the fiber due to air dust would be higher if the output is set higher, and
the laser beam might be diffused.
To prevent damages on the system, please use the laser of less than 100mW. Use of
higher than 100mW laser may damage the CSU-X1 system.
Use of control, adjustment or performance of procedures other than those specified
herein may result in hazardous radiation exposure. Never use lasers outside of the
specification.
NOTE：
NOTE：
Recommended laser specification:
Range of wavelength: 405nm to 647nm.
Laser power: 100mW of less at either input to the CSU-X1 or fiber output.
The best efficiency of laser coupling by the coupler is 50% or more. To examine
laser outputs from your laser system and the fiber, it is recommended to use a
power meter for measurement.
