Maybe these diodes require an absolutely clean lens. Maybe typical residue on, well, anything will burn and damage the window? As if you have to treat it like opening up a harddrive. No dust whatsoever anywhere.
Something I have noticed about all the N diodes from the A series on up is they have a hot spot in the center of the output. We have all seen how when focused to infinity that when burning wood/paper up close that its always the center of the box shaped output spot that burns first. Some diodes may have a higher center concentration of energy than others. It's possible that the duty cycle of these will have to be limited when being pushed hard. Now if the substrate can live without the can/window then great. Time will answer both these questions.
