The lead selenide detectors are also available in a quad version with four channels: an attractive alternative for gas measurement.
When applying PbSe detectors, it was previously necessary to use either several single detectors or filter wheels to detect different wavelengths. Our solution saves you space in your system, time when measuring, and costs in procurement.
Four selected PbSe chips are arranged in quadrants and equipped with their own filter. The readout of all channels is carried out simultaneously. For an improved signal in the long-wave range, we also offer cooled versions.
Advantages
With these new detectors, you can measure and analyze gas mixtures simultaneously – this is fast. In addition, you save space: instead of four single detectors or a filter wheel, you can simply use a TO-8 or TO-39 housing.
Pyro or PbSe?
Quad detectors have been available with pyroelectric detectors for years; they are generally used for gas analysis. In some applications, a higher D* value or higher speed is desired – both of which are offered by lead salt detectors. The same filters are used for pyroelectric detectors and PB detectors. As a manufacturer of both versions, you can not only rely on our neutral advice regarding different technologies, but you also have a particularly large selection of gas filters available. We also offer the assembly of your own filters.
