L and M Band -BUTTERFLY NEBULA
Particle Dimming In The Mid IR
With these simple calculations it is easier to "resolve" why the M band has superior resolution as unwanted interference is removed
R<3% 0.532µ Rav <2.5% 1-5µ R<0.5% 4.8µ A.O.I.=0º
This Astrophysicist wanted to study several NIR and MID IR Filters while noting a particular efficiency at 4.8µ and simultaneously reducing the 532nm line for the alignment of his Optical Light path. Even though M has the lowest extinction J, H, K, and L are also significant as they reveal more information about our Universe
