Becker and Hickl have released an ultra-fast version of their HPM-100 series hybrid detectors. The new HPM-100-07 detector has an IRF width of less than 38 ps, full width at half maximum, including the pulse width of a bh BDS-SM-405nm ps diode laser. The HPM-100-07 contains a Hamamatsu R10467-07 hybrid detector tube together with a preamplifier and the generators for the tube operating voltages in a single compact housing. The principle of the hybrid detector yields excellent timing resolution, a clean TCSPC instrument response function, high detection quantum efficiency, and extremely low afterpulsing probability. The absence of afterpulsing results in a substantially increased dynamic range of TCSPC measurements.
