`
`The lenses are being shipped today for delivery on Monday. (If I don't hear, I'll assume they have arrived.)
`
`Jerry - could you give us a couple of dates for our overall schedule?
`- prototype assembled (pre testing)
`-CDS internal testing completed - ready for projector testing
`
`It would also be useful to have an indication of what you expect in terms of "on projector" testing from your point of view.
`
`
`Thanks,
`
`
`Matt.

`Matt:
`
`
`Thank you for the call to clarify some of my questions and your description of the lens zoom
`movement is also clear. It's very much appreciated.
`
`
`Any idea what the status is for those lenses to ship to CDS?

`
`To clarify the lens movement issues - Biggest picture (=widest projection angle) with the lens elements extended
`as far as possible out of the projector.
`
`
`Movement from over zoom range covers about 41mm. At its furthest extension it is about 2mm behind the
`outside ring on the lens
`
`
`Barco projector
`The lens on the Barco is 40.7 - 50.9 mm. the lens element movement is about 40mm, with it being 1mm behind
`the outside ring on the lens in its extended position. (this was tested without turning on the lamp so it is not
`known whether the lens follows the same behavior as the Christie lens - it is assumed that it does - and will be
`tested later.)
`
`
`Note that Minolta makes almost all the lenses for the DLP cinema projectors for all manufacturers, so lens
`behavior among different projector brands will be consistent.

`
`Lenny and Matt:
`
`
`While I digest Matt's input, could you provide the exact screen width and throw distance in
`Clarity theater when using 1628 pixels or 2048 pixels? Also, could you determine if the
`diagram I attached in my last e-mail and attached here again is correct? Thank you.
`
`
`One point to clarify now is, based on Matt's comments, is TR of 1.45 meant for full size DMD?

`Ying-moh:
`
`
`1. We need a system that will work for both situations. What are the implications of different projection
`distances and different angles? The Clarity is approximately 52' throw and 26' screen width. Lenny can
`probably dig up exact numbers.
`
`
`2. The throw ratios are complicated by using less pixels of the DMD.
`
` if the throw ratio is 1.45:1 using 2048 pixels of the DMD, then using 1628 pixels, the ratio of
`screen width (usable) to distance becomes 1.82:1 Our image is narrower that the maximum
`that the lens can handle, but our object (DMD pixels) are also narrower. You are right that the
`

`
`

`
`full width DMD angle at 1.45 is 38 degrees - clearly beyond our design target. But using only
`1628 pixels, the angle becomes 30.6 degrees (slightly over design). In the El Cap theatre the
`lens setting will be slightly narrower than 1.45 (1.47 I think) which brings the angle below 30
`degrees (by a tiny amount.)
` I don't have the Clarity lens at my finger tips, but the labeled focal range should be something like
`40.6mm and 50.4mm - Lenny can you look at your notes on this?
`
`Maybe I'm not being clear - and we should discuss this on the telephone?
`
`
`3. We would like to design for both flat and scope modes. My suggestion would be to design for 30
`degrees in Flat mode and all situations will be covered.
`
` some theatres are "common height" meaning that the side curtains go out for scope and come in
`for flat, keeping the same height for flat and scope.
` some theatres are "common width", meaning that the top curtain goes up for flat, keeping the
`same horizontal width for flat and scope.
`
`4. Lenny can you look at the Barco lens and figure out dimensions?
`
`I am hoping that our primary design constraint is the 30 degree horizontal angle and we can
`accommodate Clarity and El Cap (different focus positions and zoom lengths) by putting shims on the
`mounting platform (of something like that). As I see it, we will have several different lens settings we
`need to accommodate, which will drive the Z location of the apparatus (distance from the front of the
`projector). Flat and scope each for El Cap and Clarity. I hope the different throw distances (52' and 71')
`between the two situations can be tuned by mirror pointing and any difference required in radius of the
`mirror can be dialed in.
`
`If the project just got more complicated, then lets have a discussion tomorrow in case I'm missing
`something.
`
`
`Matt.

`
`Lenny and Matt:
`
`I have a few questions related to my optical design setup and would like to get your
`inputs.
`
`* Would you tell us if we are designing for the Clarity theater or the El Capitan?
`* What size is the Clarity theater screen and what is the throw distance?
`* If we are designing for TR of 1.45-1.8 as Matt suggested, do we keep the throw
`distance the same for both cases?
`* Please check the attached diagram to see if it is what you understand in the lens
`retract vs TR.
`* For TR of 1.45, I calculated the FOV to be 38 deg. and the focal length to be
`32.33mm when projecting 1628 pixels
`wide. f=0.5*1628*0.01368/tan(19)=32.33mm. This focal length is outside of your

`
`described 50.7-67.8mm. What am I missing? Do you actually project TR of 1.45 in
`Clarity theater?
`* Do we design for the "flat" mode with 1.85:1 aspect ratio?
`*
`
`
`Hope to get your input on the above soon. Thank you.

`
`That should have been as follows:
`
`
`This is a good question. The lens on the Barco on my floor which has
`a zoom range of 40.7 - 50.9 mm moves through a little more than
`30 mm. The front element translates from recessed to flush.
`
`
`The Clarity theater lens which is 50.7 - 67.8 retracts from flush to
`more than a 45 mms.

` Matt:
`
`
`How much does the lens need to move to go from TR 1.45 to 1.8? I think we may
`have up to 20mm space to accommodate the focus change but and the other lens type
`but we need at the mechanical design to know for sure.

`Jerry et al:
`
`
`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.
