ING filter database; narrow band filters

This page is automatically updated each time the FILTER ORGANIZER program is used to log filter movements. This page was last updated: 03 Oct 06 11:36 .

The filter throughput specifications (check out the links!) have been measured by Mariet Broxterman from Dec 1996 onwards. The filter scans run upto 9000A; the determined centroid wavelength of I and Z band filters are affected by this.
