Close
up view of the laser frame and overmask, mounted onto the laser
table. A mask has been cut out and removed, and the overmask
remains bolted to the table between the laser frame pieces. |

shimstock (0.003" thick, black annodized) overmask after a mask has
been cut out by the laser, and the aluminum laser frame bottom. |

A
snapshot of a F-1 aluminum shimstock mask and ruler positioned on top
of a paper drawing of a FLAMINGOS-2 mask. The drawing shows the
outer dimmensions of the mask and the positions and sizes of the
mounting holes. If our laser table had enough travel, we would fabricate a frame larger than this outline, to hold the mask material. After laser cutting all of the slitlets (some fake slitlets are shown in the drawing), the second to last step is to use the laser to cut the 8 mounting holes (3.18 mm in diameter), and then the final step is to cut out the boundary of the mask. It then falls out of the laser frame, leaving behind what I've called the 'overmask'. |
