Short Throw Projector

If you have had any involvement with a brick and mortar business or organization, chances are you've been to your fair share of meetings. In today's technological environment, almost every presentation is created with slide-show software and displayed via a projector. However, many projectors are designed to accommodate larger halls where they are placed very far back in comparison to where the screen is positioned. Often times, these will not function properly in a very small area such as a confined conference room. Don't despair though, because there is a specific device for this problem which is the short throw projector.

Short throw projectors are unique in that they can display full quality images and videos onto a large screen from a very short distance. This is beneficial because it can be used without worry of a shadow being cast from the projector light bulb and the person at the front of the room.

When buying a short throw projector, read the specification sheet for the particular model and you will generally see a feature known as the throw ratio. This number is a ratio of the distance from the projector lens to the screen to the actual screen width. A big throw ratio will equate to a longer distance from the projector to the screen, however these optical systems tend to be more focused than their shorter throw counterparts. The convenience of a short throw project should not go unnoticed, because they can be used in a wider variety of situations, such as the home theater or aforementioned business meeting room.

The throw distance (distance from the lens to the screen) for a short throw projector can be as low as 0.5 feet, or as high as 8 feet. With this in mind, it's best to do a little math before hand and take a few measurements around the room where the projector will be placed.

If you already own a projector but need to upgrade to a short throw projector lens, that is also a viable alternative to buying a new system. These can cost anywhere from $500 to a few thousand, however they will give you the flexibility to move your projector to several locations should you want to transfer it from room to room. Many brands do come with a short throw attachment when you purchase them, including Casio, Hitachi, InFocus, Panasonic, Sanyo and NEC to name a few.

Whether you want your own home theater or you are a business owner looking to upgrade presentation quality, you can benefit from adding a short throw projector to any room of your house or office.
