FOUR CHANNEL LEAD SALT DETECTOR, the MIRA4 Jul 10, 2009

Custom or standard narrow bandpass optical filters attached to each of the four elements, e.g. for gas sensing CmHn, CO2, CO, ref.

The detector/filters are hermetically sealed into a compact industry standard TO-5 can with sapphire window. Other window materials can be used instead.

Sensitive in the 1-5 micron wavelength region, the detector output after filter attenuation is dependant upon the applied bias to the detector, filter specifications, and temperature stability of the detector package. Crosstalk is minimized between optical channels to less than 0.5%.

Compared to using four individual element detectors, MIRA4 can reduce sensor cost in a system by as much as 60%. The compact and low power requirements of MIRA4 makes it suitable for portable measurement equipment.

MIRA4 is well suited for use in a variety of applications including industrial and medical gas analysis, auto and aviation emissions analysis, underground applications such as mining tunnels and walkways, and general environmental monitoring such as smoke stacks and assembly lines.
