beam spot size

The PCB Magazine, November 2015

The PCB Magazine, November 2015

…limitations on the smallest via diameter it can reach. One limit is caused by light diffraction. Specifically, the smallest focused spot size to which a laser beam can be focused is directly related to its wavelength. Longer (e.g., far infrared) wavelengths, cannot be focused as finely as visible…

…from 10 kHz to 30 kHz. A beam parameter product of typical 20 mm x mrad (for a 400 μm, round core output fiber) enables this power to be effectively concentrated into small focused spot sizes. The unique combination high average power, high pulse energy and superior beam quality makes the HighLight…

…upgrade. And if you’re already using AVIA lasers, upgrade is very simple because AVIA NX is backwards compatible delivers exactly the same unmatched beam parameters as earlier models and uses common software commands. The end result is lower cost of integration, lower cost of ownership and greater…
