2.4.6 Filter Holder Installation

Identify the access doors used to install the neutral density FILTER HOLDER and the four

interference FILTER HOLDERS. The small access door located near the top edge of the left

side panel on the Lambda DG-4/5 cabinet (see below) is for the neutral-density FILTER

HOLDER. The larger door in the middle of the left side panel is fro the interference FILTER

HOLDER. Loosen the black knob on these access doors to slide them up and install the

appropriate FILTER HOLDER into the slot. The bottom of the neutral density FILTER

HOLDER is flat while the bottoms of the interference FILTER HOLDERS are grooved. For

this reason, these two types of FILTER HOLDERS are not interchangeable. Make certain

that the end nearest the filter cup goes in first.
