In short

SPADλ is a linear detector with a 320×1 SPAD array. It features single-photon detectors (SPADs) enabling both photon-counting and photon-time tagging. This arrangement is ideal for spectral detection applications. Thanks to microlenses and state-of-the-art production facilities, this detector offers high detection efficiency. The detector is capable of both time gating and time stamping for the ultimate control over time-varying signals of interest.

Key benefits

Prism spectral

Linear detector array

SPADλ features a single line with 320 single-photon detectors. This form factor is suitable for spectral applications that require high-speed, low light performance and/or single photon timing.

Wide detection spectra

Wide detection spectra and low noise

Our single-photon detectors are fabricated in a state-of-the-art CMOS process and offer a low dark count rate of less than 250 cps. Microlenses enhance the detection with a peak detection efficiency of over 45%.

Timing resolution

Time tagging and gating

The sensor features both time tagging and time gating to study time varying signals of interest, this offers the most flexible approach to filter out unwanted signal while still preserving the arrival information of single-photons.

Plug-and-Play

Plug and Play

The system requires just a 5V power adapter and two USB3 cables to run. For full flexibility, 4 additional control lines can be connected to the SMA connectors. The industry standard C/CS-mount optical port and the M4 screw mounting positions offer a flexible integration into any existing optical setup.


SPADlambda integration

System integration

The detector is bundled with an intuitive software interface. The software gives easy access to all functionalities offered by our detectors, allows for fast prototyping and makes acquiring single-photon data easier than ever. For the advanced users, we offer full remote control through a standard TCP/IP interface. This enables the user to take full control of the system from any TCP/IP capable software package, such as Matlab, Octave, Labview and Python.
