SPH-40 Series: Discrete Pyroelectric Detectors.
Current Mode, Super High Voltage Response, Low Noise.
A family of devices that feature our LiTaO3 detectors mated to a state of the art current mode, operational amplifier circuit with 1011 chip resistor that results in incredible voltage response... 50,000 V/W and a detectable signal level of nanowatts.
The CM circuit is designed to allow the user to adjust bandwidth and voltage output for optimum performance. It is available in five element sizes from 1 mm to 9 mm diameter, packaged in TO5 or TO8 cans.
Options include the application of an Organic Black coating and choice of IR windows to shape their spectral response.
Take a look at our SPH-CM-TEST Test Box as an easy way to power the SPH-40, change Rf and Cbw while evaluating its performance.
- Responsivity to 50,000 V/W
- Detectivity to 1.3 x 108 cm(Hz)1/2/W
- Bandwidth 1Hz to 10KHz
- 1 mm to 9 mm diameter
- Optional IR windows
