Is your laser’s focus spot where you think it is? This video shows the focal shift of a 100 kW laser during the first four seconds of startup using BeamWatch, Ophir-Spiricon’s non-contact high power beam analyzer.

Sometimes a laser is used in a “pass-through” setup, which begs the question: What happens to the laser after it passes through?
Consider for example a sensitive camera that is used to profile a laser. Beam splitters are often used to deflect only a small percent of the laser intensity into the camera. The other 90% or more passes straight through the splitter.
For every wavelength of laser along the electromagnetic spectrum, Ophir-Spiricon can measure the output. This video briefly introduces the equipment used in the different regions of the spectrum to measure and profile lasers.
