WebIn order to monitor only light at 800 nm, filters must be used to eliminate the higher orders. First order wavelengths between 200 and 380 nm may be monitored without filters because wavelengths below 190 nm are absorbed by air. If, however, the instrument is evacuated or N 2 purged, higher order filters would again be required.
