I would be very interested in seeing the results from using these filters.

Note that they are intended for industrial applications rather than 
photographic applications.  Edmund states that the "Thermoset ADC 
filters have the highest transmission and lowest haze".

What does lowest haze really mean?  It may well be the case that the 
filters are not appropriate for photographic use.

If anyone does do a reasonably controlled test of the filters I would 
be delighted to include the results in the Infrared FAQ.
