`Mahir:
`
`I have not revised the design since receipt of Matt's new requirement. I will see if I can get some
`progress on that this evening. So, I'll come see you tomorrow at about 12PM? Please
`confirm. Thank you for your flexibility.

`Ying-Moh,
`
`I agree we should go over the mechanical design, especially in light of the change in lens specs. I can meet
`anytime tomorrow. I also have some questions about what the clear apertures would be necessary to
`accommodate the changes Matt is requesting.

`
`I am not in sync with your packaging in terms of optical component placement. I suggest that we
`schedule an 30min. to 1 hour meeting to go over your design and see what we can accommodate for
`this focusing requirement. I can come later today or noon tomorrow. What's convenient for you?
`
`
`Jerry: Do you think we should have an internal design review on all the details?

`What are your comments to Matt¡¦s email? Do we have room for focus adjust and how much room to
`accommodate a different lens.

`
`
`We will be providing you with two lenses.
`
`
`The primary one we want to work with is 1.45 to 1.8. (I don't have drawings but from memory it is the
`one with the extended hood that needs to be machined off.) The secondary one is the 1.8 to 2.4. The
`1.45-1.8 lens is the one used essentially all the time in the Clarity theatre.
`
`
`We understand that the intended working cone angle is 30 degrees (full angle) maximum and that this
`means about 1.8:1 actual throw to width ratio. Because we use less than the full width of the DMD, the
`advertised number for the lens represents a wider picture than we actually achieve, so in fact in our
`operation for flat pictures using 1628 of 2048 pixels horizontally, we are at a throw ratio of about
`1.5 referencing the full width DMD, but equating to 30 degrees full angle.
`
`I hope this is clear - if not perhaps we should have a quick telcon to make sure we are on the same
`page.
`
`
`One point I was thinking about - Focusing the lens consists of moving it in and out of its mount via a
`sliding mechanism. This will change the actual location in the Z dimension of the end of the lens. Have
`you allowed for adjustment (a one time set-up) in this dimension to accommodate this focus
`movement? It is probably what is also required to accommodate two different lenses.
`
`
`Matt.
