Transmission data for the KPNO Mosaic Wolf-Rayet CIII filter (k1021)


Below are the transmission curves for this filter in parallel light on different dates.

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 bluer. See the plot at the bottom of the page.

Below is a plot of this filter as simulated in different f/ratio beams. At the KPNO 4m f/3.1 the properties of this filter are:
CWL=4657A FWHM=52.6A PEAK TRANSMISSION=68.23%
