Collimators enable long-range testing to be performed in a compact environment. The relay lens elements produce a virtual image of a target focused at a long distance. Typically, these are focused around the hyperfocal distance or up to infinity. The Imatest Collimator Fixture helps with the precise alignment required when using this system.
The Imatest Collimator Fixture includes a validation procedure that ensures minimal work-distance error and an on-board computer that displays and saves camera positions, lens and light panel configurations, and simulated distances. The Fixture is adaptable to numerous camera systems by providing adjustable simulated test distances, interchangeable collimating lenses, and a variety of test charts. The Fixture integrates with Imatest LED Light Panels, sizes C through G, and includes a joystick and computer-control interface for automatic positioning using four motorized stages, and storage and recall of device positions.
