Superconducting Transition Edge Sensors （TESs） are promising optical photon detectors, which can count infrared photons with energy information. TES characteristics are explained in terms of a readout system with a negative feedback circuit. The current status of the optical TES detector development is introduced. We also introduce the development of our Ir-TES. Further optimization of the readout circuit is anticipated by using the recent fast cryo-electronics.
