I can verify the wavelength is between 250 and 300nm using optical bandpass filters. UV reactive items fluoresce when using a ZWB1/UG11 filter (which has a cutoff below 250nm), but cease to fluoresce when using a ZWB2/UG1 filter (which has a cutoff below 300nm). Item arrived well packed from HotRed, but there was still some crush damage to the lens which seems to have been preexisting. It won't affect my use this time, but it should be addressed.
