Iodine Stabilized HeNe

Stabilized Laser Reference for the WS8-series

Iodine Stabilized HeNe

Stabilized Laser Reference for the WS8-series

The Iodine stabilized Helium-Neon laser system is an easy to use calibration system for all high-end wavemeters. Because it's reference frequencies base on the transition of atomic iodine isotop vapour, it is ideal for calibration of our wavelength meters of the Ultimate accuarcy series!
 

Main Benefits and Properties:

  • Fully compliant with the International Committee of Weights and Measures CIPM 97 “Mise en pratique” recommendations for the realization of the meter
  • Frequency repeatability: 2.5 x 10-11
  • Frequency stability: 3 x 10-12
  • Compact construction
