Lasers & Blood

How Lasers Count Your Blood

You have your blood drawn at the doctor’s office or hospital, and sometime later you get the results. The complete blood count (CBC) tells you the levels of components in your blood. Have you ever wondered how those numbers are determined? Did you know lasers play a key part in getting that data? Well, we’re going to unpack it all right now.

How Lasers Mark Things

How Lasers Mark Things

Did you know that today you are surrounded by things large and small that have been permanently marked with a laser? From the SIM card in your phone to the milk container in your refrigerator and the control panel of your washing machine, laser marking is everywhere. Read why and how lasers make all these different marks.
