UMass Amherst researchers have developed a laser-based holographic alignment method that could revolutionize overlay accuracy in semiconductor manufacturing, though its industrial adoption may hinge ...

It’s a rare person who can pick up a cheap laser pointer and not wield it like ... That’s a small target to hit without some alignment help, which [Les] uses a range of hacks to accomplish.

The laser pointer was installed in the gun using a set of 3D printed rings to make sure the alignment was correct. It’s powered with a Sparkfun battery pack and control board which all fit into ...

Innovative laser alignment methods enable precise imaging of biomolecules, advancing single-particle diffraction techniques ...
