Chapter 7  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 disassemb

led 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.
