About the authors

Dana Busheri-Nehama is the main editor for the Ophir Photonics laser measurement blog and also serves as Marketing coordinator at Ophir Photonics. Although new to the world of laser measurement, she takes a no-nonsense approach to the blog: if it doesn’t interest our readers, it won’t be published. Dana has a degree in communication and strategic planning and a lot of experience in running blogs but more importantly – she always knows how to bring the best, most updated content – in every field she chooses to cover.

Dana is no physicist, however a unique combination of skill sets, including creative writing and a love of the hard sciences enables her to thrive in the hi-tech blog environment. This, and the support of Ophir’s many laser-measurement experts, means that Ophir’s blog should be your first stop when searching for answers to your laser measurement questions.
