If anything, I actually prefer the original Ten-Tec filters in this case
because they were totally sealed/enclosed and thus may prefer superior
crosstalk etc isolation to the unsealed Inrad filters. This is totally
opposite to the case for Omni 5/6 filters where Ten-Tec made unsealed
filters (which also tended to lose spec over the years) and the IR filters
were sealed.
