…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…

…develop mode-hop noise during its lifetime. With ultra low-noise capability, the spatial qualities of the laser beam do not change, allowing the beam to be focused on the same spot size, profile, and shape.

…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…

…achievable spot size (numerous other factors also influence memory capacity). Changing to visible light sources would overcome the limitation, since they would yield smaller spot sizes for the same M2 value. Visible DPSS lasers obviously provide a high-quality mode, but their current size and cost…

…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…

…when using lens-based objectives. These beam delivery optics can achieve a homogenized spot with a diameter as small as five (5) microns, which is ideal for sampling small fluid inclusions. The optics also include interchangeable circular and square beam shaping masks providing high sampling…

Focusing Units

Focusing Units

Focusing Units With a focusing unit the parallel beam from the collimating unit is focused down to the workpiece. The size of the focused spot and the depth of focus are given by the ombination of collimating optics, focusing optics and beam quality. The Optoskand focusing units come either with a…
