From the date of July 1, 2006, specified electric and electronic equipment (mainly consumer equipment for individual consumers) sold in this market are subject of RoHS (Restriction (of the use) of Hazardous Substances) application in EU member nations.

In accordance with this directive, following six toxic chemicals are restricted from usage.

Specified six toxic chemicals include lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chrome (Cr (VI)), and polybrominated biphenyl ether (PBDE) and Polybrominated biphenyls (PBB), which are flame retardant plastic.

This directive is one of the EU Environmental Directive series and is closely related to WEEE (Waste Electrical and Electronic Equipment) directive.

Under RoHS Directive, the products which includes material exceeding the allowed maximum concentration (ratio to the weight) must not be sold. (At the present date of July 1, 2006)

The allowed maximum density is 100 ppm (0.01%) for Cadmium and 1000 ppm (0.1%) for the rest of materials. (However, the allowed density is higher in some subject materials.)

As the awareness toward environmental preservation increases as a theme of all mankind, Chuo Precision Industrial Co., Ltd. is approaching toward RoHS Directive to restrict a use of hazardous materials in our products.

The latest information regarding products that comply with RoHS Directive will be published on our site.

If the density information of each product is necessary, please contact our sales department.

It is believed that our glass optics (optical elements) described in this catalog can meet the requirements under RoHS Directive in accordance with conditions for the allowed maximum concentration which have been announced officially by EU's TAC (Technical Adaptation Committee） or Annex 13 of 2005/747/EC Directive. As the latter 2005/747/EC's Annex 13 approves exemption from application of such requirements to glass optics and filter glass products for optical application, and allows the use of lead and cadmium which are often contained in such products. As a result, these products "comply with" the RoHS Directive (2002/95/EC Directive).
