The VISERA 4K UHD surgical endoscopy system delivers images in 4K resolution (4096 x 2180 pixels) and Ultra HD (UHD) with 3840 x 2160 pixels, providing four times more image information than conventional Full HD imaging systems. It generates a wider color gamut by adopting the 4K color format (BT2020) and allows surgeons to observe fine patterns and structures in high precision.
