years experience in photon counting !
Founded in 1993, Becker
& Hickl have introduced a proprietary time-correlated single-photon
counting principle that made TCSPC more than 100 times faster than the
existing devices. Moreover, bh introduced a multi-dimensional TCSPC
process that records the photons not only versus the time in the signal
period, but also versus other parameters, such as experiment time,
wavelength, or spatial coordinates. The bh devices are designed to
record multi-dimensional photon distributions, time-resolved images,
sequences of photon distributions, or multi-dimensional time-tag data.
The bh TCSPC products are complemented by bh picosecond diode lasers,
detector modules, multi-spectral detector assemblies, and experiment
control modules. Based on these components Becker & Hickl supply their
own confocal fluorescence lifetime laser scanning microscope and FLIM
upgrade kits for laser scanning microscopes of various manufacturers.
Moreover, bh is supplier of TCSPC modules for commercial time-domain
optical tomography instruments. bh market activities include currently 5
workshops around the world and distribution of more than 1200 pages of
