Introduction
The IRL 715 is an incandescent lamp of size T-1, i.e. max. diameter 3.17 mm. It has been
specified to be employed in gas detectors based on infrared (IR) absorption. The accessible
wavelength range amounts from the visible up to about 4.4 μm.
The IR-source is especially well suited for the detection of carbon hydroxides at 3..3.5 μm and
carbon dioxide (CO2) at around 4.15...4.4 μm. For this application the modulation frequency can
be chosen up to 3 Hz. There is only a limited suitability of the source for the detection of carbon
monoxide (CO) around 4.6 μm, since for this band the glass transmission is already decreasing.
The cut-off wavelength is at 5 μm.
