RE: Dodd-Frank Wall Street Reform and Consumer Protection Act: Section 1502 - Conflict Minerals
Diffraction International undertakes due diligence to attempt to determine if 'conflict minerals' are used in our products. Conflict minerals are defined as Gold (Au), Tantalum (Ta), Tungsten (W) and Tin (Sn) that are sourced from the Democratic Republic of Congo or adjoining countries from mines controlled by non-governmental military groups.
We have reviewed our existing products to identify those that contain the above named minerals. The list is short and the quantities small, so we here state the details in full:
Diffraction International's primary product, CGH Nulls, contains no Gold, Tantalum, Tungsten or Tin.
Diffraction International uses Tungsten (W) carbide rods (~300 gm/year) in the assembly of its CGH multi-axis positioners. These rods are sourced from Ultra-Carbide and manufactured by G-Elit Hartsoffe GmbH and/or Konrad Friedrichs GmbH & Co. KG. Documents obtained from Ultra-Carbide conclude with a statement that: "We have with due diligence, ensured that none of the materials we or our suppliers use are conflict minerals and can therefore be labeled as DRS Conflict-Free as defined in Sec. 1502.(b)"(1)"(D) of the Dodd Frank Act".
Diffraction International uses tiny amounts (<100 gm/year) of Tin (Sn) alloy solder in the assembly of its phase shifter products. This solder is a product of Henkel Electronic Material LLC (P/N MM01876). Henkel
confirms that "there is no indication that any products manufactured by the Electronics group of Henkel contain conflict minerals".
We therefore state that no products manufactured by Diffraction International contain conflict minerals.
