How to Measure Laser Exposure

Usually, laser measurement focuses on power or energy, (or both). In some cases, however, the total energy exposure needs to be measured. Exposure means the sum of all the energy that hits the target (be it metal, electronic wafer, or human skin). Two common cases where exposure is key are medical lasers and photolithography. In…

How to Profile an Ultraviolet Excimer Laser

Ultraviolet excimer lasers are important for many applications: primarily medical and photolithography, but not exclusively.  Measuring them, however, is not always so simple. We recently encountered a company that needed to know how evenly their excimer laser beam was distributed in space.  They tried imaging their beam with specialized ultraviolet cameras, but all they got…

How to Calibrate Your Laser

If you use a laser seriously you probably already know that just because you turn the knob up to 100 W, there’s no guarantee that the laser is outputting 100 W of power. First, why should you calibrate your laser? Contact us
