SHORT THROW PROJECTORS

If you're not using a short-throw projector, we think you should be, for a number of reasons.

When buying a projector, there are many factors to consider - such as the size of the venue it will be installed in, or the type of system it will be plugging in to - to say nothing of budget. Projectors typically mounted on the ceiling in the middle of a classroom or at the back of a cinema are known as 'long-throw' projectors - where the image is projected or 'thrown' a relatively long way.

As predominant as these types are, there are two key problems with them - image interruption from blocking the projection, and more importantly, disruption and even damage of vision to the presenter by accidentally looking directly into the beam of the projection.

Short-throw projectors all but eliminate these problems. Designed to deliver a super-sharp image from a very close distance to the screen, these units place the audience and the presenter behind the light source - so no one can accidentally get their head in the way of the image or catch a blinding beam of light in the eye.

Short-throw projectors are being recommended more and more by government for teachers, who risk regular retinal exposure to bright projector lamps. They can be installed just about anywhere, just as longer-throw projectors can be, and are available in a wide range of types, from units integrated into whiteboards, to desktop mini units.
