6" Attenuation Filter Box

Installing this 6" filter box into my optical bench setup was straightforward thanks to the precise filter slot alignment, and it has noticeably cleaned up the signal with zero leakage.

The mounting slots on this filter box are machined precisely, so the optic sits perfectly square without any wobble. I paired it with a standard 6" mirror and the alignment held steady through a full afternoon of testing. A solid, no-fuss piece of kit for the bench.

The filter slides into the 6" holder perfectly snug, and the attenuation feels even across the whole surface. I wish the included case had a bit more padding for transport, but the box itself does what it's supposed to do.
