Lumex SNR-40633 MicronSensIR™ Integrated Detector Assembly
|
Lumex's MicronSensIR™ Integrated Detector Assembly incorporates electronics while still providing the exceptional sensitivity of the 2mm2 PbSe detector across the 1 to 5.5 micron spectrum. Ideal for portable instruments where size, durability, and costs are so important, this compact detector provides a 10dB gain amplifier, a cooler, and a thermistor all within a hermetically shielded package. This configuration helps minimize system noise, optimizing the measurement dynamic range, while reducing the system footprint and costs.
The MicronSensIR™ Integrated Detector Assembly design takes advantage of a shielded, high impedance detector node to minimize noise. With the integrated thermistor and thermoelectric cooler (TEC), MicronSenseIR™ Integrated Detector Assembly can manage temperature fluctuations reliably. These complementary features combine to optimize the signal to noise ratio. The standard MicronSensIR™ Integrated Detector Assembly also supports single or bipolar bias supplies.
Features

Lumex SNR-40636 MicronSensIR™ Infrared Emitter
|
Lumex's high-performance MicronSensIR™ Infrared Emitter combines a high-speed pulsable emitter with its corresponding drive electronics on a compact 14 pin circuit board. Designed to maximize output over a 1 to 200Hz range of pulse speeds, these complementary assemblies enhance signal to noise performance, while minimizing the overall system footprint. The construction and implementation of the emitter and control circuitry optimize performance by matching the drive waveform for the desired operating frequency. This ensures peak output temperatures at all pulse frequencies and promotes the highest output for any application. With typical pulse speeds of 180Hz and 50% modulation depth, even trace elements in low parts per million concentrations can be accurately detected. The MicronSensIR™ Infrared Emitter sub-system is an ideal solution for a variety of applications. The control circuitry will exploit the capabilities of the high-speed source in any application, pulsed or steady state.
