Go down to the rifle range and fire a few rounds at a target 100 meters out. Chances are you won't hit the bull's-eye. Even if you read the wind right and don't twitch as you're squeezing the trigger, you may well fall at the first hurdle: lining up the shot.

Aiming a weapon is harder than it looks. Shooters need clear views of a distant object (the target) and a near one (the iron sight at the end of the rifle barrel) at the same time. But the eye can't quite pull this off, as a simple experiment shows: Point at a faraway house or storefront, then try to bring both your finger and the building into focus. One or the other will be blurry.

Idaho National Laboratory's innovative gunsight technology, the MicroSight, helps the eye solve this problem. The MicroSight, a disc smaller than a dime, brings both the target and the iron sight into simultaneous focus, giving marksmen a better sight picture. The new sight has national-security applications, as it could improve safety and performance for American soldiers. Millions of target shooters and hunters should also benefit.

"The MicroSight gives you much of the performance you'd get out of a holographic or telescopic sight," says INL engineer David Crandall, who developed the technology. "But it's more reliable, much lighter-weight and much cheaper."
