   Insight Product Company is proud to offer Multi-Channel Optical Photon Registration System. Insight Product Co. offers superconducting single photon detectors and ultra-low noise registration systems for the visible and near infrared range. All systems operate in continuous mode, no gating required.

   The system is based on fiber-coupled NbN superconducting single photon detectors and can have several independent channels (up to 4). The superconducting detectors require cryogenic temperature, and Insight offers two type of cooling systems.

Advantages:

-Frequency range includes coverage into higher frequencies than other photon counters on the market.
-Short dead time (10 nanoseconds) compared to long dead time (microseconds) of alternatives. Therefore rapid repeition rate of 10s of MHz possible, whereas alternative have -maximimum repetition rate of 1-10 kHz.
-Very small dark counts (10/second) compared to high dark count (1,000s / second) of alternatives. Does not require gated mode unlike alternatives. Works in continious operation mode.

Therefore device can detect CW signal, which is impossible for the alternatives.

1) Liquid Helium (LHe) based system

The system is designed as a cryogenic insert placed inside a standard LHe Dewar.

This allows the use of superconducting detectors without the need for expensive special cryogenic equipment.

The LHe storage Dewar, filled with 100 liters of helium, allows up to 2 months of uninterrupted operation of the system.

The main advantage of this system is higher quantum efficiency. There are detection systems available for two spectral ranges:

 

Spectral Range

Quantum efficiency referred to optical input

0.9 - 1.7 um

more than or equal to 22% at wavelength = 1.0-1.2 um

more than or equal to 20% at wavelength = 1.31 um

more than or equal to 16% at wavlength = 1.55 um

0.6-1.7 um

more than or equal to 25% at wavelength = 0.7-1.1 um

more than or equal to 14% at wavelength = 1.31 um

more than or equal to 10% at wavelenth = 1.55 um

2) Cryogen-free system

The closed-cycle refrigerator is a cryogen-free cooling system that does not use liquid helium (operating temperature 2.5 degrees Kelvin).

This type of detection setup would be ideal when the investigator wants to avoid handling liquid helium.

The close-cycle refrigirator can operate uninterrupted for months from an electrical power source. There are cryogen-free detection systems available for two spectral ranges:

 

Spectral range

Quantum efficiency referred to optical input

0.9 - 1.7 um

more than or equal to 20% at wavelength = 1.0 - 1.2 um

more than or equal to 15% at wavelength = 1.31 um

more than or equal to 12% at wavelength = 1.55 um

0.6-1.7 um

more than or equal to 18% at wavelength = 0.7-1.1 um

more than or equal to 10% at wavelength = 1.31 um

more than or equal to 7% at wavelength = 1.55 um
