`
`Jerry,
`
`Josh said that he would deal directly with ColorLink.
`
`Mike Porter is the purchasing agent and he should be able to supply tracking numbers.

`Matt:
`
`We have not received the lenses yesterday – they should be here today. If you have a tracking number we can
`follow it through the system.
`
`The long lead item on the schedule is going to be the Color Link ½ wave plate. I understand you have some pull
`with them. If you want we can send you the quote from them and you or someone else from RealD can help us
`expedite the order.
`
`I will have a better idea what the schedule is one we hear back from the suppliers – all of the drawings will be out
`this week for quote and delivery. We did have an internal design review and made a few minor changes from the
`configuration presented at the Final Design Review.
`
`I will get you the schedule by the end of the week.

`
`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.

`
`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?

`
` Clarity - Christie projector
`
` Lens in the Clarity appears to be 1.8 to 2.4 (50.7 - 67.8 mm)
`
`
`
` 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.
