1.0 Product Introduction

 

1.1 Handling Scientifica equipment – precautions 

 
This section contains important safety information related to general use 
of the Scientifica Scanhead. It is a piece of scientific equipment and as 
such requires care when handling.  
 

• Before use, carefully read the instructions, including all 
warnings and cautions. 
• Inspect the product, any cables, and connectors before each 
use.  
• Do not use any equipment that appears damaged. 
• Do not apply excessive tension to any cable. 
• There are no user serviceable parts inside the unit. 
• Always disconnect the instrument from the power supply prior 
to cleaning the system or performing maintenance work. 

 

Adjustment or removal of any screws or components 
other than those noted in this manual can adversely 
affect the performance and operation of your device and 
may invalidate your warranty. 

 

The Scanhead requires a dangerous class IV infrared 
pulsed laser product, which produces hazardous, 
invisible laser radiation that can permanently damage 
your eyes. It is therefore, strongly advised that the 
correct Personal Protective Equipment is used when 

handling. Please consult your laser manufacturer or the 
laser manual for more details. 

 

Alignment of the class IV laser into the Scanhead should 
always be done at minimum power and the wavelength 
of the laser tuned into the edge of the visible range

. This 

is in order to minimise output from the laser and reduce the 
efficiency of mode-locked pulsed operation. Some laser 
manufacturers also provide an alignment mode, which 
operates the laser at safer output powers. 
 
 Never switch the top diagonal mirror of the Scanhead when 
scanning or aligning as this will cause the beam to be 
reflected and exit back out of the input port.  Never look 
down eyepieces when scanning or aligning as this may 
result in eye damage.
