1. Find Projectors
Dukane Projection Distance Calculator
There is a very useful tool for those considering any one of the 30 Data-video
projectors available from Dukane. It is called the Dukane Projection Distance
Calculator. This interactive chart will help to determine the correct location for a
Dukane for any given screen size.
The Projection distance calculator can be found here:
http://www.dukane.com/av/products/ProjectorCalculator.asp?
Any one of the 30 currently available Dukane projectors can be found and used within
this chart. Over 100 “Historic” projectors, (another word for End of sale or discontinued)
projectors are included for those that have and use those projectors.
If projector terms and terminology are new to you, or if you encounter an unfamiliar
term you can find a glossary of projector terms, and how they relate to Dukane
products here:

Also, chart showing all of the currently available Dukane projectors can be found here:

2. Projectors can be sorted in many ways. You can sort them by brightness, by weight, by
resolution, and of course by price. But one of the most useful ways to compare
projectors is by throw distance, the distance and projector “throws” the image to the
screen.
Here are screen shots from several different types of projectors.
I have used a one constant in each example: a screen width of 120” inches or 6 feet.
Most modern classrooms or conference rooms are 12 feet from ceiling to floor. It is
hard to generalize about the size of screen used. While a 12 foot wide screen ‘could”
be used, the 4 feet closest to the floor would be blocked if students are seated in
typical rows. Some classes have bigger screens, some have smaller. The most widely
used size of IWBs (interactive whiteboards are 77” Diagonal and thus have a screen
width of at most 59 Inches( allowing for the borders of the board) or about 5 feet wide I
chose 6 feet width as a median size for the purpose of this explanation.

3. Ultra short throw: As the name implies , an ultra short throw distance has a very short
throw distance
This chart shows the Dukane Imagepro 8104HW will fill a 6 foot wide( 120” Diagonal)
Screen from a distance of 3.25 feet.

4. You can also see each chart offers additional useful information. You can compare a
ceiling or floor( or desk) mounted position. The chart also takes into consideration the
ANSI lumens ( brightness) rating for each projector and ambient room light .
Short Throw Projector. The throw distance is less than a standard projector , but still
closer than a projector with a standard distance
You can see the screen distance on this unit is 6 feet from a 120” wide screen. That is
not as close as an ultra throw short throw projector , but closer than standard throw.

5. Standard Throw Projector :
This standard throw projector is ideally placed 16.4 feet away from a 120” wide screen

6. Long Throw Projector :
The Long Throw projector is ideally 18.7 feet from a 120” wide screen.
The reason for a long throw projector is that it can be placed at the rear of a room and
its lens will allow the image to fill , without oversizing a screen at the front of the room.

7. In most cases with a long throw projector is used , in a larger classroom or training
room a larger screen would also be used, but these examples were done keeping the
screen size of 120” wide as a constant.
Finally, an example of an Historic Model
The Dukane 8020A was sold 20 years ago. There are still models of this unit in use.
The point is simply that Dukane wants the users of Dukane products to make good use
of them for as long as they are still viable.

8. This projector may seen antediluvian but it came out at the time when the average data
video projector was only 500 lumens( this is 750), had a 150:1 Contrast ration( it had
300:1) and when many projectors were only VGA( 400x600 pixels) and this was
SVGA( 800x600).
