Face
view of a single MOS frame prior to annodization (290 KB).
A ruler, a Flamingos-1 mosplate (black rectangle inside of frame) with
length = 105 mm), and a paper cutout of a F-2 mosplate are shown for
scale. The tab in the upper left of the paper cutout is where the
mos-id barcode may be located.

Face
view of a single MOS frame and the mock-up of a single slot of the MOS
wheel (296 KB). A ruler is shown for scale. The frame
slides into the slot from the left, and the tab at the right of the
frame slides underneath the copper fingers in the slot.

MOS frame installed. The copper fingers hold the tab of the MOS
frame.

A
full-size F-2 Mos plate, cut from paper. A full-size GMOS barcode
is stuck to the paper mask; the sheet of barcodes to the upper left is
a sheet of GS2003A program barcodes, printed onto Avery stick-on labels
(from Michael Ledlow, during my visit to Gemini South over
Thanksgiving, 2003).

A
close-up view of the paper mask. I cut out one of the barcodes
from the sheet, and stuck it on the paper mask. The upper barcode
is the human-readable format interleaved 2 of 5 barcode used by GMOS;
the lower barcode is of some unknown format. The F-2 Symbol
Technologies barcode reader will be programmed to read interleaved 2 of
5 barcodes.

When
the mask is installed in the frame, the tab carrying the barcode sticks
out past the frame. The MOS wheel will have a pocket large enough
for this tab. The barcode reader is at room temperature, and only
may see the barcode region when the MOS port access cover is off, as
when someone is loading MOS plates. The 2of5i pattern clearly
extends past the frame, as does the human-readable text (11021301).
