Not available on OEM lasers
When integrating Novanta OEM lasers, the Buyer and/or integrator of the end system is responsible for
meeting all applicable Standards to obtain the CE mark. To aid this compliance process, Novanta testing
program has demonstrated that lasers comply with the relevant requirements of 2014/30/EU, the
Electromagnetic Compatibility Directive, as summarized in the table below.
