Notes
The Throw ratio for a particular
lens is fi xed, but assumes that
the image fi lls the width of the
DMD.
For images that do not fi ll the
width of the DMD, the Throw
ratio is effectively increased.
To correct for this in these
calculations, a Throw Ratio
Factor (TRF) is used.
The lenses available and their
part numbers are listed below:
1.0: 1 fi xed lens 103-350
1.25 - 1.45: 1 zoom lens 103-351

Choosing a lens by calculation
For any screen size not listed above, or if you need to be more precise, then use the
calculations below.
Identify actual width of the image in pixels.
Calculate the Throw Ratio Factor: TRF = DMD width (2048)
Image width in pixels
Identify the screen width required.
Identify the throw distance required.
Throw distance calculations are based on the distance from the outer end of the
lens, which will vary from lens to lens. Once a lens has been chosen, the fi gures
can be checked using the more accurate fi gures given on the next page.
Calculate the throw ratio required. Throw ratio = Throw distance
Screen width x TRF
Choose a lens with the required throw ratio from the list to the right.
example
An unresized image, 1280 x 1024 pixels, screen width 11m, throw distance 26m
from the outer end of the lens.
Throw Ratio Factor (TRF) = 2048 = 1.6
1280
Throw ratio required = 26 = 1.48

Lens extension is measured
when the lens is focussed at
infi nity, and fully extended.
At other focus settings, the
extension could be up to 10mm
less
Useful lens calculations
The following lens calculations may be useful:
Throw ratio = Throw distance
Screen width
Throw ratio factor (TRF) = DMD width in pixels = 2048
image width in pixels image width in pixels
Therefore:
Screen width = Throw distance (from outer end of lens)
Throw ratio x TRF
Throw distance = Screen width x Throw ratio x TRF
The throw distance calculated above is to the outer end of the lens. For each lens,
the nominal distance between the front of the projector and the outer end of the lens
(lens extension) will be as listed below:

105-453B January 2007 Page 2.15 Digital Projection LIGHTNING 35HD-T, 40HD-T User Manual 2. Installation Notes Each time a new lens is fi tted to the projector, the calibration procedure must be carried out. See Lens menu, in Section 4. Using the menus. Be careful not to scratch the lens surfaces. If you do accidentally touch a lens, then clean the surface using a lens paper. The zoom drive mechanism should always be set to the engaged position, even when using the non-zoom lens, as it provides an extra level of protection, should the lens release lever fail. Fitting the lens Turn the lens release lever anti-clockwise to open the lock. Turn the zoom drive mechanism anti-clockwise to disengage the drive. Insert the lens into the lens aperture, making sure that the two notches on the lens engage with the locating tab inside the lens mount. Turn the lens release lever clockwise to lock the lens in place. When the lock is fully closed, the lever should feel loose. Turn the zoom drive mechanism clockwise to engage the drive. • • • • • Lens release leverZoom drive mechanism

Using the menus, Lens menu. If the lens is to be shifted in two directions combined, the maximum range is somewhat less, as can be seen below. full horizontal and vertical shift without distortion combined shift without distortion is reduced total lens mount shift available in pixels and vs DMD size Shifting the image The normal position for the projector is at the centre of the screen. However, you can set the projector above or below the centre, or to one side, and adjust the image using the Lens shift feature to maintain a geometrically correct image. Any single adjustment outside the ranges specifi ed below may result in an unacceptable level of distortion, paricularly at the corners of the image, due to the image passing through the periphery of the lens optics. If the lens is to be shifted in two directions combined, the maximum range without distortion will be somewhat less, as can be seen in the diagrams to the right. The maximum range available with no distortion is dependent on which lens is used. The tables below show the maximum range for images that fi ll the DMD. For images which do not use the full height or width, extra shift will be possible, up to the limit of the lens mount movement. 1.0 :1 fi xed lens (103-350) vertical (pixels)horizontal (pixels)vertical (vs DMD height) horizontal (vs DMD width) ± 400 ± 256 ± 0.37H ± 0.125W 1.25 - 1.45 :1 zoom lens (103-351) vertical (pixels)horizontal (pixels)vertical (vs DMD height) horizontal (vs DMD width) ± 540 ± 365 ± 0.5H ± 0.178W 1.45 - 1.8 :1 zoom lens (102-451) 1.8 - 2.4 :1 zoom lens (102-676) 2.2 - 3.0 :1 zoom lens (102-677) 3.0 - 4.3 :1 zoom lens (102-678) 4.3 - 6.0 :1 zoom lens (104-189) vertical (pixels)horizontal (pixels)vertical (vs DMD height) horizontal (vs DMD width) ± 282 ± 172 ± 0.26H ± 0.085W It is physically possible to shift the lens further than this, up to the number of pixels shown in the diagram to the right. However: There will be some distortion of the image beyond the ranges specifi ed above. Due to internal hardware layout, the shift towards the upper-right is limited as shown in the diagram. Due to continuing product development, these fi gures may vary by ±25 pixels. • • • • • 640 (0.31W)384 (0.19W) 560 (0.52H) 135 449 520 (0.48H)
105-453B January 2007 Page 2.17 Digital Projection LIGHTNING 35HD-T, 40HD-T User Manual 2. Installation Notes BEFORE INSTALLING THE PROJECTOR, READ ALL THE WARNINGS BELOW AND ALL THOSE IN IMPORTANT INFORMATION AT THE FRONT OF THIS MANUAL. The projector weighs over 100kg (200lbs). Use safe handling techniques when lifting the projector. Make sure that the surface, ceiling or rigging that is to support the projector is capable of supporting the combined weight of the projector and lens (see specifi cation for weights). Backup safety chains or wires should always be used. Do not tilt the projector more than ±12° from side to side when in use, as this may cause serious lamp failure, damage the lamp module and cause extra cost on replacement. The projector my be tilted forwards and backwards as necessary. Mounting the projector The projector is designed to be suspended from a lighting truss by its rigging frame. However, the four adjustable feet under the chassis allow the projector to be lowered onto a fl at surface without any danger of hands being trapped between the bottom frame and the surface. Levelling Before suspending the projector, make sure that the three frame adjusters are set roughly midway. Coarse frame adjustment If the projector is to be suspended by its rigging frame, coarse adjustment of projector level should be made by adjusting the length of the supporting wires or chains, or by adjusting the position of the truss. Fine frame adjustment Once the initial coarse adjustment has been made, fi ne adjustment should be made by turning the three frame adjusters on the rigging frame. The frame adjusters will provide approximately ±10mm of movement relative to the rear right corner. Centering lines are scribed on the shafts to show the centre of adjustment. Chassis adjustment If the projector is to be operated from a fl at surface such as a projector table, then adjustment of projector level should be made by turning the four feet under the chassis. Centering line Frame adjuster ±12° 360°
Page 2.18 105-453B January 2007 2. Installation Digital Projection LIGHTNING 35HD-T, 40HD-T User Manual Notes When stacking projectors, the stack MUST be vertical, to ensure that the stresses are distributed to all for frame couplings. Make sure that the surface, ceiling or rigging that is to support the projector is capable of supporting the combined weight of all the projectors and lenses (see specifi cation for weights). Do not place heavy objects on top of the projector chassis. Only the rigging frame is capable of withstanding the weight of another projector. Do not try to stack more than four projectors. Separate backup safety chains or wires should always be used for each projector. Stacking projectors The rigging frame is capable of supporting the weight of up to three other projectors, using the built-in frame couplings. The projectors can be stacked on top of each other, or suspended below each other. Carefully lower each projector down onto the top of the others, making sure that all four frame couplings engage fully. Fit a locking pin into each coupling. A ball in the end of the pin prevents the pin from falling out – to insert or remove a locking pin, press the button on the t-bar to release the ball. Align the images from the projectors, following the instructions in section 3. Getting started, Adjusting the projected image. • • • Frame coupling Hole for locking pin
