Many of the wavelengths given here are measured in mm - for instance, InGaAs is noted as having a range from 900 mm to 1000 nm but with special techniques can measure at 1700 nm. This is strange, as 1700 is between 1000 nm and 900 mm.
Is this a typo?

Looks like it's already been changed to nm which is pretty clearly what was meant.
Does anybody have good images to add of photocathodes. The article is a little bare with them. ElectronsNStuff (talk) 19:33, 26 December 2020 (UTC)
