Many laser applications use pulsed beams, and pulse widths are becoming very short – even fs pulses are …
This video explains why the Spiricon Pyrocam pyroelectric camera is the overwhelming camera of choice for laser beam diagnostics of IR and UV lasers and high temperature thermal imaging for scientific research to industrial high power lasers to safety and defense applications.
Lasers are used for many different applications and come in a large variety of powers and parameters, so it wouldn’t be fair (or logical) to require the same sort of safety measures for industrial laser welders as laser pointers or barcode scanners.
There are many ways to measure laser output: You can use a photodiode, thermopile, or pyroelectric sensor. This …
Struggling to keep the quality of your industrial laser process consistently high enough? You’re no alone. Modern production …
As every year – Ophir’s new 2020 catalog for laser power measurement covers a wide range of laser …
“Additional error with frequency”. What does it mean? Why does it happen? Read all about that in this week’s blog post:
Pyroelectric sensors are the tool of choice for measuring energy of repetitively pulsed laser beams.
They measure energy, and they’re fast.
They are not, however, indestructible.
Disclaimer: Don’t do anything stupid.
What I’m about to tell you is a trick that should NOT be used lightly.
However, in many cases Ophir sensors can be used for far higher powers than in the spec, as long as it’s only for a short time exposure.
If your application involves a laser which is not always on the target, such as the following setup, you might need a beam dump. Consider this: The deflectable mirror is used to direct the laser to its intended target
