Product Details Supplier Info More products

Aurea Technology has released enhanced versions of its SPD A and SPD B single-photon counting modules for applications in the near-infrared (NIR) spectrum including fluorescence spectroscopy and photoluminescence. These modules are available from AP Technologies.

The systems are based on Aurea’s InGaAs avalanche photodiode technology.

Aurea has made the time-correlated single-photon counting (TCSPC) option available for both modules: SPD AT and SPD BT. In both cases, customers can specify a single-channel or two-channel design.

Key specifications

  • The systems operate from 900-1,700nm
  • SPD A is optimised for use in the range 1,100nm to 1,600nm
  • SPD B is intended for shorter NIR wavelengths and is optimised for 1,000nm to 1,350nm
  • The modules now feature adjustable dead-time and faster electronics
  • Users can operate the counter up to 20MHz without compromising sensitivity

AP Technologies Ltd
