Green and Blue Laser Welding
Laser welding, cutting, or cladding has become increasingly popular and, in most cases, has been performed at the NIR wavelength region. However, NIR lasers are less efficient for copper processing due to high reflectivity and therefore low energy absorption. Copper absorbs just 5% of the laser energy at 1070nm, but up to 40 % at…

Understanding Dynamic Range…The Numbers Game
There is a fair amount of confusion caused by the reporting of dynamic range of beam profilers. The purpose of this blog post is to explain some of the terminology used in the discussion of this parameter by both Ophir- Spiricon and other suppliers of beam profilers. Definition Dynamic Range is the ratio of the…

Laser Measurement Systems: Best Practices
Given the pace at which technology advances, there always seems to be a learning curve. With the abundance of consumer electronics available, there typically is no right or wrong way to use these devices — the choice usually comes down to the method that best suits the end user. However, when purchasing a highly advanced…

Evolution of Measurement Technology for Laser-Based Additive Manufacturing Systems
Ophir BeamPeek, integrated power measurement and beam profiling In laser powder bed fusion (LPBF) processes, metal powder is selectively melted layer by layer using a laser beam. With layer thicknesses of typically 30 to 120 µm, exact adherence to the predefined beam parameters is an essential prerequisite for ensuring that the structures generated exhibit the…

Updating software for older beam profilers: When quality becomes a challenge
We attach great importance to quality when developing and producing our measurement technology. And to great effect: With proper handling and regular maintenance, many of our measuring devices can continue to be used long past the expected end of their service life. However, this longevity can become a real challenge for some beam profilers that…
