Comparison of images captured at (a) SGC, Oxford with the Minstrel HT and (b, c) Novartis, Basel with the Rock Imager. SGC droplets are captured at one focal depth, resulting in out-of-focus regions, whereas Novartis images are a combination of seven focal depths and hence are sharper across the droplet. The pllate material, seals and optics used at Novartis also produce colour gradients in the images. |
