OSIRIS Filter Reports

Filter Reports

The table below shows the filters installed in OSIRIS. The table is split up into two sections, one for the Spectrometer portion of OSIRIS (SPEC), and one for the Imager portion (IMAG). The Central Wavelength, Bandwidth, Cut-On/Cut-Off Wavelengths, and Transmission data listed in this table are based on the 50% transmission points. All data are for filters at operational temperature (77K).

Combined OSIRIS Filter Plots:

Plots showing relationship of Broad Band to Narrow Band filters:
(Only done for SPEC filters - IMAG filters very similar.)		 SPEC Z-band
SPEC J-band
SPEC H-band
SPEC K-band
All Broad Band filters on the same plot:
(Only done for SPEC filters - IMAG filters very similar.)		 SPEC Broad Bands
All filter plots in single PDF file with all above individual: SPEC Filters
