Detector LRM-254 | Great Potential Inside Small Dimensions
Dresden, Germany — Even smaller, even stronger – this is how we might describe the new LRM-254 detector by InfraTec in just a few words.
This miniaturized four-channel detector in TO39 housing, with a diameter of only five millimeters, has just expanded the product range of the Dresden manufacturer, InfraTec.
A mere glance at its appearance gives clues about this sensor’s first unique feature.
In the cap where conventional multi channel detectors have sensitive narrow bandpass channel filters with special adhesive mounted, a central window has been added in the detector cap instead.
This significantly more robust broadband filter, e. g. made of sapphire, offers substantially better protection against penetrating moisture. It can also be soldered to the housing to create a complete hermetic seal.
The channel filters are now placed inside the detector instead. There, they are shielded from mechanical and physical stress, as well as from other strains from harsh environments – and they are also located even closer to the pyroelectric elements. (more…)
