All microscopes, objectives and oculars as well as the transformer boxes were checked and cleaned by the SERCO contractor Emile Meylan. This is the list of findings:


Microscope property numberMicroscope TypeDiagnosis
90871 Axioscope A1 POLStage counterweights had to be cut down which was accomplished for all three specimen holder sets of that type on board
90869 Axioscope A1 POLXY stage faulty (inner pulley system problem), Serco can’t fix this, needs to go back to Zeiss – tested 3 other stages, 2 out of 3 are broken and will be send to College Station to be forwarded to Zeiss
91187 Axio Imager A2

- known issue with PCBA board, which has missing parts on order,

- scope is set up for fluorescence, unsure why in that spot

91188 Axio Imager A2 (MBIO)

No issue reported.

90229 Axioplan POL

Bertrand lens is de-laminated, attachment not useful, so it was removed.

90207 Axioscope POL (Thin Section)

No issues reported.

90257 Axiophot

Stage couldn’t be moved far enough to focus on specimen, it was discovered that gear inside wasn’t lined up, Serco had to remove focus knob covers and align 15 O-rings back to where they are needed in order to move stage to correct positions.

Recommendation from Serco – don’t tinker with inner workings of scopes if not absolutely necessary, send to Zeiss or have Zeiss rep service call.

91060 Stereoscope

Magnification knob doesn’t stop at 1x or 8x, no way to fix it as body is glued shut. Stored in Imaging Lab as fall back for high usage expeditions.

90812 Stereoscope

No issue reported.

91105 Stereoscope

No issue reported.

90811 Stereoscope

No issue reported.

90812 Stereoscope

No issue reported.

90228 Stereoscope SV11 (reserve in Imaging Lab)

No issue reported.

ODP00584 Old grey stereoscope (reserve in Imaging Lab)

No issue reported.
