Transmission data for the KPNO Mosaic OIII +29nm Offband filter (k1015)


Below is the transmission curve for this filter in parallel light.

Note that there is a shift in central wavelength when placed in different f/ratio beams. At the KPNO 4meter f/3.1 beam this corresponds to a shift of approximately 12 Angstroms bluer; at the CTIO 4meter f/2.9 this corresponds to a shift of approximately 15 Angstroms bluer; at the WIYN 0.9m f/7.9 this corresponds to a shift of approximately 5 Angstroms redder. See the plot at the bottom of the page.
