Chapter 9  Regulatory 

As required by the WEEE (Waste Electrical and Electronic Equipment Directive) 
of the European Community and the corresponding national laws, Thorlabs offers 
all end users in the EC the possibility to return “end of life” units without incurring 
disposal charges. 

 

This offer is valid for Thorlabs electrical and electronic equipment: 

 

Sold after August 13, 2005  

  Marked correspondingly with the crossed out 

“wheelie bin” logo (see right) 

 

Sold to a company or institute within the EC  

  Currently owned by a company or institute 

within the EC  

  Still complete, not disassembled and not 

contaminated 

As the WEEE directive applies to self contained 
operational electrical and electronic products, this 
end of life take back service does not refer to other Thorlabs products, such as: 

 

Pure OEM products, that means assemblies to be built into a unit by the 
user (e.g. OEM laser driver cards)  

 Components 

 

 

Mechanics and optics  

 

Left over parts of units disassembled by the user (PCB’s, housings etc.).   

If you wish to return a Thorlabs unit for waste recovery, please contact Thorlabs 
or your nearest dealer for further information. 

Waste Treatment is Your Own Responsibility 

If you do not return an “end of life” unit to Thorlabs, you must hand it to a 
company specialized in waste recovery. Do not dispose of the unit in a litter bin 
or at a public waste disposal site. 

Ecological Background 

It is well known that WEEE pollutes the environment by releasing toxic products 
during decomposition. The aim of the European RoHS directive is to reduce the 
content of toxic substances in electronic products in the future. 

The intent of the WEEE directive is to enforce the recycling of WEEE. A 
controlled recycling of end of life products will thereby avoid negative impacts on 
the environment.
