Haiou Photoelectron Technology (http://www.e-otron.com) provides the latest foreign single-photon counting module, wavelength 400-1100nm and 800-1700nm series, the module photon detection efficiency can reach 48% at 550nm, each detected a photon generates a of TLL pulse output, can also be provided with a digital interface and sampling system, direct USB connection to the computer, and the supporting software and complete the program count support. Usually module using conventional circuit design, if the design of fast circuit, can reach than 50ps better time resolution. Due the epitaxial silicon avalanche diode detectors and iAQC design can achieve high the photoelectric detection efficiency and time resolution, the unique design and perfect performance more suitable for time-resolved photon counting, fluorescence analysis, quantum encryption.
