Quartzlock Products


The E10-CPT is designed using the Coherent Population Trap (CPT) method. In comparison with the traditional atomic clock, there is no cavity and the lamp has been substituted with a Laser spectrum lamp. The E10-CPT has low power consumption and miniaturization has been realized in the CPT atomic clock with the procession of MEMS
