An attractive multi-gas sensor can now be designed around our new quad PbSe detector, especially suited for low signals and reduced cross-talk, when before single point detectors with rotating filter wheels would be needed. Each chip within the quad has its own optical filter, selected from a large range of 17 standard filters. Custom types or free-issued filters by customers are possible.
Greater sensitivity for longer wavelengths is achieved with cooled versions, using an optional integrated thermoelectric cooler. Four simultaneous signals are possible in now a smaller space and with faster reaction time, all within a TO-8 or TO-39 housing.
