How to calculate image resolution The detail in an image is determined by resolution. The shorter the lens focal length, the wider the field of view. Greater than about 90° most lenses start to show curved, barrel distorted images that compress the image at the edges. Rectilinear lenses such as those using Theia Technologies' Linear Optical Technology™ don't exhibit barrel distortion and thus maintain image resolution out to the edge of the image. Resolution has many definitions; no one definition is correct for all situations. Resolution can be specified in pixels per foot or meter at the object. This mapping of the image sensor dimensions onto the object is most intuitive for calculating what level of detail can be seen in the image. Fundamentally it is the horizontal field of view of the camera divided by the horizontal number of pixels. This gives a pixels per foot number that can be related to image quality. ...[More]

Nick Steele, Special IT Projects, Salem City School District, Salem, NJ says

"We used Theia lenses in our high school for the main hall ring and outside in the parking lots using 5 megapixel cameras. Every installer we contacted said the angles were way too aggressive and wanted us to double our cameras and halve the angles at the very least. We actually got into a few heated arguments with a few vendors and installers. We did the math, and we knew the camera could pull it off, we just had to find a lens that could prove them all wrong.

We went searching and the only thing that met our specs was the Theia lens. Jaws dropped when they saw the pictures; not only did we get the massively wide angles we needed, but we did it without the fisheye everyone told us was impossible to avoid, and every single dot in the 5.1 million pixel image is fully utilized and warp-free.

We still shake our heads in disbelief when we walk by a flat panel showing these lenses. We could not have done it without Theia. You guys are not only one of the only choices for such wide angles, your lens output outperforms everything there is. There is no higher quality wide angle lens on the planet!"

Theia's lenses can be seen on a few webcams. See one at the Acme Oyster House in New Orleans.
