Theia Technologies - Calibrated Lenses

Theia’s calibrated lenses are individually characterized and calibrated at the factory to provide a rich array of data sets.  This calibrated data makes the lenses easier to use by allowing accurate conversion from intuitive units to lens settings.  The calibrated data is also provided to allow image resolution optimization for fast and accurate machine vision applications. Many of Theia's calibrated lenses are motorized varifocal lenses allowing flexibility of setting the focal length and focus distance remotely and automatically.  Motorized adjustable lenses have many applications including image optimization for barcode reading in mobile robots, variable image field of view for improved navigation, quick set up for non-fixed cameras, and many more.  These benefits are enabled with calibration data frames which may include MTF resolution performance, focal length, F/#, geometrical distortion, relative illumination, and more. This calibrated data is provided so the user can optimize image quality in real time and possibly without the requirement to use difficult or costly field calibration fixtures.    Calibrated data is a combination of data unique to one lens and design data that is common across lenses in the same family.  This data is available for download from Theia’s cloud database along with application notes providing some options for using the data and motor control firmware and software for quick integration into a custom program.
