• blue side cutoff due to glass dye; reasonably rapid cutoff
• red side cutoff due to multi layer interference film
• overall good efficiency
• overall little ripple

Conclusions
• There are a variety of B band filter profiles• One has a large asymmetry towards the red• Most are nearly symmetrical• Best choice for SNAP needs to be explored• In our longest NIR passband, a redward extension
is a serious contributor to our dark current owing to thermal tails of warm objects within our telescope
• We should explore symmetrical passbands
