IMACS Filter Servers

 

Final assembly, test, and integration - February, 2003

1

New filter insertion stages. Note the single-acting air cylinder, reduced size of insert arm, and rotationally symmetric key.

 


January, 2003

2

Old filter insertion mechanism. The two-stage insertion arm, which includes a double-acting air-cylinder, was revised to minimize space constraints, and delete the rotationally sensitive key mechanism.

 


Early Filter Server System Fabrication

The filter server system (FSS) provides an automated filter change capability for the IMACS short and long cameras. Each of the two servers carry a set of 20 removeable filter frames. A DAEDAL motion stage positions a cassette holding the filters.
A two-stage air-powered insertion mechanism delivers the filters into the operation position inside the camera barrel.

 


FSS is mounted on a red engine stand for testing.
