Temperature Stabilized Fabry Perot Etalon for Cs spectral filtering

Display dtc03andetalonv3

FPE001B is a temperature-stabilized Fabry-Perot Etalon designed for spectral filtering in Cesium experiment. The extinction ratio at 9.2GHz is -38dB.The mK adjustability of the temperature controller minimizes effort in the optimization of transmission. The ultra-stable temperature design allows time-consuming, photon-counting experiment. It is a convenient tool for EIT and quantum memory experiment.
