Hi,

I'm looking for a high-precision & high-speed method to measure the
entrance angle of a Laser-beam.

I have a probe that is illuminated with a HeNe-laser. I would like to
equip the probe with some kind of sensor that cam measure the entrance
angle of the laser beam.

Are there any buyable sollution? Which company is selling sensors for
this application?

Thank you for your help.
