This product has been discontinued, as part of Coherent’s ongoing environmental initiative.  Coherent is leading the photonics industry with our commitment to environmentally-sensitive manufacturing and applications.  This effort includes bringing our entire product line into compliance with the European Union’s RoHS (Restriction of Hazardous Substances) directive – including laser measurement instruments, even though these products are not within the scope of this directive because they fall within Category 9 of the directive. 

Coherent is balancing this program with a commitment to support our customers through this transition as we phase certain products out.  For this reason, all affected products will be phased-out gradually, in order to allow customers sufficient time in which to transition to a new, green product.   If you are using FieldMaster to measure both power and energy, the FieldMaxII-TOP is a good alternative that offers similar features and functionality. If you are measuring only power, the FieldMaxII-TO and FieldMate are good alternatives.  Follow this link to learn more about Coherent’s green strategy.
