The following filters
are currently available in LWS. See below for plots of filter
transmission curves compared to the atmospheric transmission
measured for Mauna Kea.
Wavelength range over which filter transmission exceeds 50% of peak.
The transmission data and wavelength calibration are in
agreement with manufacture's data.
Nwide cannot be used for imaging. The 5 micron bandwidth results in excessive
background levels and saturates the detector. The SiC filter is better
suited for broad band imaging with LWS. Nwide is used as a blocking filter for
Filter transmission over the 10 and 20 micron atmospheric windows.
The atmospheric trasmission spectra are calculated by Lord, S. 1992, NASA Tech. Mem. 103957. The filter transmission curves are taken from the table above.
