Chapter 10  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.
