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.
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.
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.
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%.
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.
