DISCRETE-MODE LASER DIODES

EP1854 Discrete-Mode Series – H2O Sensing

Choose any wavelength from 1850nm – 1880nm

 

The EP1854 Discrete-Mode Series laser diode builds on Eblana Photonics extensive experience in longer wavelength InP processing.

The ability to interrogate higher sensitivity absorption lines in the 1850nm – 1877nm region makes this laser suitable for many moisture sensing applications ranging from pipeline to semiconductor fab.

 

Popular wavelengths:

  • 1854nm (5394cm-1)
  • 1877nm (5328cm-1)
  • 1850nm (5405cm-1)
