`Matt:
`
`I’ve taken a look at the schedule and it is holding to what we presented at the FDR. All the
`mechanical parts are out for quote and should be on order next week. This is typically a 3-5
`week cycle – hopefully less. The long pole is probably the ½ wave plate and Joshua is looking at
`this with Color Link.
`
`
`We still need a Zscreen to complete some final details regarding mounting them to the
`structure. Please send a representative sample ASAP.
`
`
`Thanks

`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?

`
`I think our communications are lining up.
`
`
`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.

`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
`

`Exhibit 2154-5
`MASTERIMAGE 3D, et al. v REALD INC.
`IPR2015-00035
`
`

`
`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.
