Keysight
5517 C He-Ne
The Keysight / Agilent 5517 C is a helium-neon (HeNe) laser. The 5517 C has an output power of 491 µW. The 5517 C operates at a split frequency of 2.81 MHz.[1]
What it is
The Keysight 5517 C is a He-Ne laser.[1]
How it works
General reference — not yet source-verifiedA He-Ne laser generates coherent visible light from a gas discharge in a sealed optical cavity.
A precision optics laser of this class provides a stable optical output for measurement and alignment tasks.
Where it fits in the process flow
General reference — not yet source-verifiedA He-Ne laser of this class belongs in optical metrology and alignment work rather than in wafer processing.
