  Eliminate distortion in wide angle images Today’s megapixel cameras have many advantages as long as you have the right lens for the job. When that includes covering large areas or reducing cost by installing fewer cameras, that lens is a wide angle lens. Until recently only fisheye lenses were available for an ultra wide field of view. Fisheye lenses create a curved and distorted image which no one seems to like. This significant distortion causes loss of resolution at the image edges. In the past year a new rectilinear lens giving a different ultra wide view without the barrel distortion or loss of edge resolution of fisheye lenses has been developed. This report is an overview of wide angle lens technology and how we overcome fisheye distortion using Linear Optical Technology. ...[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. The calculator should help deterine the best application of Theia's lens.

•  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.
