Criterion is proud to have a long working relationship with the Center for Applied Optics (CAO) at the University of Alabama in Huntsville (UAH). The CAO has over 25 years of experience in the design, analysis, fabrication, testing and integration of optical sensor systems from the lab to the space environment. Together, the CAO and Criterion have conceived and employed a simple qualitative dome testing system developed for use on the factory floor. In addition, Criterion and the CAO have collaborated in developing appropriate computational models and methods for the prediction of performance for a variety of camera/dome systems.
With these valuable models, our engineers can predict and prevent poor optical design elements within a system. Given today's need for complex optical forms, this service can save thousands of dollars and many months in the product development process.
The camera and the dome have to work together as a system. The best quality dome in the world will not perform well unless it is designed with the camera and lens in mind. Criterion engineers working with CAO have developed the specialized ability to evaluate a dome's potential for optical distortion as it relates to camera position - including the challenge of looking above the horizon.
We have developed several proprietary methods for producing hemispherical domes that transition to a straight side above the horizon. These designs involve complex geometry to improve clarity and minimize distortion.
