Short Throw Projectors: Create Big Images in Small Spaces
A short throw projector allows users to create big pictures in tight spaces, without concerns about shadows obstructing the image or light shining in the presenter’s face.
Short throw projectors have very short throw ratios, the distance from projector to screen compared to the screen size. For example, a projector with a 1.5:1 throw ratio would have to be 7.5 feet back to project a 60-inch diagonal image. Short throw projectors like the Hitachi CP-A100 (pictured), which boasts a 0.37:1 throw ratio, can project the same large image from just 1.4 feet away from the screen.
They were designed with educators in mind.
“Education is the main driving force behind the short throw market,” Keith Yanke, NEC Display Solutions’ director of product marketing, recently told Gearlog.com. “Installation and integration is usually cheaper when using a short throw model because you are installing the projector to the wall and not on the ceiling. This means lower mount costs, lower cable costs and less labor.”
In addition to cost-savings, short throw projectors are also more flexible than their traditional counterparts. Educators can use them at the front of the classroom, rather than the back. No more worries about little feet tripping over the cables.
Short throw projectors are made with a higher quality lens than traditional projectors, according to Gearlog. They may also employ a chipset that “pre-warps” the image so it can be projected from a short distance.
