White papers about Theia's wide angle technology. The most recent addition:

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]

What to expect from Theia's ultra wide rectilinear lenses.

Theia's ultra wide no distortion lenses are designed for applications where an ultrawide field of view is required. These applications include general surveillance of parking lots, warehouses, construction sites, etc. Theia's lens is not designed to be a facial recognition or license plate recognition lens.

Theia has developed a Big Picture™ Webinar that can be downloaded and helps to understand the ideal application of Theia's technology.

Image resolution calculator and field of view calculator for Theia's ultra wide lenses.

Theia's lenses are designed for applications requiring ultra wide fields of view or those with restricted camera to object distance. The charts on this page will help calculate the image resolution and horizontal field of view given different camera distances.

Linear Optical Technology was developed by Theia Technologies allowing us to create ultra wide fields of view without fisheye distortion. Learn more about the technology.
