“The PERL M+ is a modern research device, based upon more than 25 years of development of my original discoveries. The PERL M+ didn’t get as good and effective as it is overnight. A lot of hard work and effort on the part of Resonant Light has gone into making improvements and what are now multiple generations of devices.

A great, state of the art device is just one part of the overall aspect to a frequency instrument. Resonant Light Technology is also the industry leader in customer service. Their multi decade commitment to helping their customers effectively utilize their instruments has been critical to the long history of successes the PERL M+ has achieved.”
