VS-HVA series Evaluation
Images are captured with low distortion from the center to the periphery of a large display, and missing pixels are visualized with high resolution.
A lens with a wide angle of view was required due to the height limitation of the device. VS-HVA series was selected as a lens that has a wide angle of view and reduces distortion to the periphery.
