My followup question is …

 

What are the chances of incerasing the upper range into the first overtone, or at least 1800 nm…?

I am interested in CH3 which, if my self taught information is correct, would respond best in the following ranges… In nm’s

700-750

875-900

1330-1400

1650-1725

Finally, the ability to look at only the overtones ranges would be VERY helpful..
