2.4.1

 

Filter Orientation 

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. 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. Remember, the light path inside the Lambda DG-4 

travels from BOTTOM TO TOP. Therefore, the filters should be oriented with their “Lamp 
Side” down. 

2.4.2

 

Loading Filters 

At the end of each filter holder is a filter cup assembly (shown below). There are at least two 

items installed into the filter cup at the factory:  a threaded retaining ring and a spacer ring 
(to carry the force of the retaining ring to the unthreaded portion at the bottom of the cup). 

In two of the filter cups, there will also be a blanking disc. Installation of filters into the filter 
holders requires care and patience to avoid damaging the threads of the filter cups and 
retaining rings as well as the filters.  

 

Figure 2-5. Filter holder assembly. 

The threaded retaining ring has two notches cut into it, 180 degrees apart. Place the notched 
end of the brass spanner wrench into the notches on the retaining ring and carefully unscrew 

it. If a retaining ring has been previously over-tightened, it is possible that the filter cup will 
begin to unscrew from the slider. If this occurs, STOP. Turn the spanner wrench around and, 
using the other end, insert it into the slots at the top of the cup. Then screw the cup back 

into the slider. DO NOT push on the cup. Just screw it in until it seats firmly. It should then 
be possible to remove the retaining ring. 
Once the retaining ring is removed, the spacer (and blank, if present) should fall out. You 
should become familiar with the assembly of this retaining system. In particular, you should 

develop a feel for tightening the retaining ring without pushing on the wrench. This is 
important because if you forcefully push on the filter holder while you are trying to load a 
filter, you run the risk of scratching the filter. 

 

Figure 2-6. Filter holder assembly with blanking disc. 

Place the desired filter into the filter cup, first. With some 1” filters extra care must be taken 
to avoid getting the filters jammed at an angle inside the filter cup.
