Photon Detection

SPCM-AQRH

Single Photon Counting Module

SPCM with free space window (right) and with FC adaptor (left), with tube cage

mount bracket and C-mount bracket (see page 11)

Excelitas Technologies’ newly improved SPCM-AQRH Single Photon Counting Module

detects single photons over the wavelength range of 400nm to 1060nm with

performance parameters superior to other solid state or vacuum-tube based photon

counters.

The SPCM-AQRH uses a unique silicon avalanche photodiode (SLiK) with a circular

active area, achieving peak photon detection efficiency greater than 70% at 700nm

over a 180µm diameter with unmatched uniformity over the full active area. A TTL

level pulse is generated for each photon detected and the signal is available at the

BNC connector at the rear of the module. The signal should be terminated into 50Ω.

The photodiode is both thermoelectrically cooled and temperature controlled,

ensuring stabilized performance despite ambient temperature changes. Operating

temperature range has been increased and the module (case temperature) will

function between 5˚C and 70˚C.

The module comes with free space window, FC fiber adaptor, C-mount or tube cage

mount bracket/adaptor options.

Recent electronic circuit improvements have reduced the minimum dead time to less

than 25ns, thereby increasing linearity and improving the dynamic range of the

module. Timing resolution of the module was also improved significantly. The SPCM-

AQRH has internal protection circuitry that protects the avalanche photodiode and the

module electronics from damage due to accidental overload from exposure to

ambient lighting.

Excelitas’ series of photon counting modules are designed and built to be fully

compliant with the European Union’s RoHS Directive 2011/65/EU.

SPCM-AQRH Series

Single Photon Counting Module

Long-term bi-stability is related to fundamental semiconductor physics and is beyond Excelitas’ control. Warranty claims will

not be considered against bi-stability alone.

Warranty claims will only be considered if the high level of the dark count exceeds the maximum level in the specification.

In the dark, the module generates random counts that follow a Poisson distribution. In a Poissonian process, the standard

deviation is equal to the square root of the average count. In this specification the “dark count variation” refers to the stability of

the average count of the module.

The actual photon rate could be calculated using the following equation, as indicated in Note #7 in the box below. This

parameter applies to the modules with dark counts of 100cps or higher.

Note # 7: Actual photon rate calculation

For the typical dead time setting of 22ns, typical maximum count rate is 37Mc/s before saturation. If the longest output

pulse width option is set (28ns), the typical maximum count rate is 30Mc/s before saturation. If the maximum dead time setting is

used, about 62ns, typical maximum count rate would be about 12Mc/s. Note that using a longer dead time will degrade linearity.

Output pulse width is set at the standard of 10ns ± 2ns at 2.2V. Other output pulse widths can be set. Please refer to Table

3, Ordering Guide, for which model number to order.

10.

Output pulse height standard is set to 2.2V ± 0.4V. Optional output pulse height is 4.4V. Please refer to Table 3, Ordering

Guide, for which model number to order.

11.

If needed, an FC fibre adaptor can be factory installed on the SPCM-AQRH module allowing optical fibres to be used. The FC

adaptor is optimized for use at 550 nm and with a 100µm core multimode fibre. If other wavelengths or fibre sizes are needed,

please contact the factory for availability. The addition of an FC adaptor will cause a small drop in the effective PDE of the module.

The amount of the loss will depend on the wavelength and the diameter of the fibre used to provide optical input to the module.

Typically, one can expect around a 5% loss with a 100µm core fibre at 550nm.

12.

Red-NIR wavelength photon detection efficiency can be optimized. PDE is enhanced over the 700-900nm wavelength range.

Please refer to the Product Brief of the SPCM-NIR series. See Figure 4 for the typical photon efficiency of standard and enhanced

PDE modules.
