There are matrix methods that can be used for propagating the diameter and curvature of the beam, but if your main interest is simply the location of the new focus (i.e. beam waist) or the size of the focal spot, you can use the Focal Spot Size Calculator tool on the Ophir website. Dr. Ivker Our expert – will explain you how
One of the really useful features of integrating spheres is that they can have multiple detector ports. Thus, more than one detector can be attached to make different measurements in parallel. As for all measuring devices, we need to understand the nature of the device because it can affect the measurement results.
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.
This video offers quick introductions to Ophir-Spiricon laser beam profiling products for additive manufacturing, high-power lasers using CCD cameras or non-contact measurement devices, BeamGage camera based profiling, no attenuation slit-based profilers and the Pyrocam camera measuring 13nm to 3000 microns.
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.
