What is a Short Throw projector? I promise it’s not what you do when your lamp dies early..
Buying a new projector can be daunting. There are so many to pick from. Especially if you need a specific type like a Short throw. What is a short throw projector you ask and why might you need one?
Sometimes your space doesn’t allow for a standard distance from the screen. Many basements and home theaters allow the projector to be installed 10-20 foot back from the screen. Occasionally you need to mount the projector very close (less than 1-5foot back). The problem then becomes the image cannot be made large enough with the standard lens. This is where the short throw projector comes into play.
A short throw lens uses a special optical design that makes it easy to position the projector close to the screen without sacrificing image size. You will see this very often in schools.
When the schools use a Smartboard system, it relies entirely on short throw projectors such as the Smartboard UF55 which uses a 20-01032-20. This lamp with housing uses an original 215W Osram lamp, projecting 2000 lumens via the projectors short throw lens.
These models use the short throw lens design to allow a 100″ image from only 2 feet away. This allows the mounts to be very close to the screen. They both utilize a standard projector lamp, part # but allow a full sized image without sacrificing space.
This can be useful at home. You can use a smaller room and still enjoy movie theater-like image sizes. The Steelcase Polyvision PJ905 with a 2002031-20 lamp is a short throw projector that supports up to a 1080p input. There are other models that use short throw lenses as well. Picking the right projector will be a series in this blog by itself so I wont go into it here.
Using a short-throw projector at home can save you a lot of setup and configuration hassle. It opens up a lot of spaces that used to not be convenient for a projector. Even if you live in a narrow apartment, a short throw projector can work in as little as 10″ from the screen. Many projectors have a short throw lens as an option. That would manufacturer dependent. Buying a lens already installed is also an option.
