Single Channel Detector

Sciencetech Single Channel Detectors

Detector Material and Spectral Region

Single channel detectors typically offer the smallest noise equivalent power (NEP values) and highest sensitivity levels. Single channel detectors are the best choice when you need to accurately measure extremely low light levels. Line and area detectors are typically used when measuring fast phenomena across multiple wavelengths (in a spectroscopic system).

Temperature Control

Some detectors can be temperature controlled or require cryogenics such as liquid helium or liquid nitrogen in order to be operable.

AC or DC Coupling

Some detectors are photoconductors and require modulated light in order to detect a signal. These types of detectors are listed as AC coupled. Generally, for AC coupled detectors a lock-in amplifier (LIA) or demodulator are required before measurements can be performed.

The Sciencetech PMH-01 Photon Counting Module is self-contained compact unit incorporating PMT tube, high-speed amplifier, discriminator, and high voltage power supply. The output signal (train of pulses, the number of which corresponds to the number of detected photons) can be sent via a BNC connector, to an external counting/displaying circuit. The PMH-01 outputs digital signal (pulses) only. There is no analog output port.

The photon counting head used has low power consumption (max 0.5W). It is already adjusted for best S/N ratio. There is no additional adjustment necessary to start the operation.

Parameter Value
Operating Temperature Range +5 to + 40 °C
Storage Temperature Range -20 to +50 °C
Effective Area 4 x 6 sq.mm
Spectral Response 185 to 900 nm
Dark Count (Typical) 400 cps
Dark Count (Max.) 800 cps

This product consists of the Sciencetech SOL-METER and our SSIVT-REF sun calibrated reference detector. The SOL-METER is a digital meter for use with solar calibrated detectors such as detector models SSIVT-REF or SC-LT. The meter converts detector measurements to a Sun value. It has a handheld meter that is compact, has a sturdy design, and is appropriate for indoor or outdoor applications.

The Sciencetech Reference Detector, which is an integral part of solar simulator calibration and solar cell I-V characterization, consists of a single element silicon detector and is designed to be used for monitoring and verifying the Sun level of solar simulators. The SSIVT-REF detector is used effective in sensing wavelengths between 190 nm and 1100 nm and is calibrated at Sciencetech against a NIST traceable calibrated reference cell. Comes with a detachable cable with 4 banana plugs for connecting to a measurement device. CE compliant.
