Description

The UltraCam Merlin stands out for its highly efficient system concept based on Bayer pattern sensors. This system maximizes the collection window and significantly reduces project costs by combining a rapid frame rate with expansive footprints. Notably, the true nadir alignment of the cones eliminates the need for interpolation, which is otherwise necessary in systems with tilted cones that produce distorted pixels instead of square ones.

The Merlin 4.1 is further complemented by our advanced image processing chain, incorporating proprietary solutions like True Pixel Processing (TPP) and Adaptive Motion Compensation (AMC). This combination guarantees precision results, elevating the UltraCam Merlin 4.1 to a new level of excellence within its Bayer pattern based system class. Two models (Merlin 4.1 2010 and Merlin 4.1 3020) are currently available.
