The two sides of a filter are usually not identical due to differences in their surface coatings.
Some form of labeling will be present to differentiate the two sides if this is the case. It is
important to refer to the filter manufacturer’s documentation to interpret the labeling and
determine the proper orientation relative to the light source.

At each filter position on the filter wheel is a filter cup assembly to hold one filter. The
Lambda 10-3 25-mm filter wheel also comes with two removable filter holders that can be
placed into the optical pathway to accommodate “fixed” filters, such as neutral density
filters. The style of the filter holder will either be “drop in” if no shutter is installed (Item 6
in Figure 1-1), or “slide in” if a shutter is installed (Item 6 in Figure 1-2).
There are at least two components installed into each filter cup or holder before the Lambda
10-3 is shipped: a threaded retaining ring to secure the filter into the cup (or holder), and a
spacer ring. In all but one of the filter cups, and in one of the filter holders, there will also be
a blanking disc. Figure 2-4 depicts these items using the drop-in filter holder as an example.
