I'm now using visual grating for SHG
I notice that IR region seems limited
I notice that soon after red region
there is a dark area followed by another spectrum
I assume that is secondary
1) how far in IR does a visual grating reach
2) do any of you guys use gold IR grating - any need or use for this
30 anything interesting in IR and anyone do any pics?
