`PBS design review

`
`To summarize:
`
`
`CDS presented their design objectives, and discussed the specifics of the design.
`
`
`Their design appears sound. It appears that they can meet all of our technical objectives, and the design
`*may* even work in El Cap (for flat anyway.)
`
`
`Their design review was very professionally handled. (we could learn from it). They logically presented
`each aspect of the design and backed it up with models. They have modeled and predicted all our design
`requirements. The completed system looks like it will meet our objectives. I gave them approval of the
`design (which triggers a payment, I think.)
`
`
`We have to take a closer look at lenses - it appears from current calculations that the 1.45 to 1.8 lens may
`be the best to design to. We need to resolve this quickly.
`
`
`The schedule shows 7 weeks to completion of the prototype, could be faster, but I doubt it.
`
`
`Matt.
