My first 18 months in photonics

It is now just over two years since I graduated from the University of Leicester with a first-class honours degree in physics with space science. I remember being asked 'Are you looking forward to taking the skills from your degree and putting them to work in the professional world?' I laughed. I had no idea how to make use of the knowledge I’d gained in Raman Spectroscopy, CMOS vs CCD technology or thermography in the real world. And yet, by the time you read this, I’ll have spent 18 months in an industry I didn’t know existed when I started my job hunt in 2020.
