Resin-embedded, heavy-metal-stained neuronal tissue images in high vacuum using the in-lens T1 backscatter electron detector at 1.5 kV. Left image shows a low-magnification overview. Images on the right represent high-magnification images from the left image, showing contrast differences resulting from backscattered electrons.
Ultra-thin, resin-embedded section of corneal tissue, imaged at 30 kV using an immersion lens in combination with the retractable STEM detector. Left image shows a low-magnification overview. Image on the right represents a high-magnification image from the left.
HeLa cell (critically point-dried on a coverslip) images with the unique Trinity In-Column Detection System. The left image (A) is taken with the T1 backscatter electron detector, which is positioned inside the tip of the final lens and shows the materials contrast. The middle image (B) is taken with the T2 secondary electron detector, which is positioned just above T1 and shows the topography information of the sample. The right image (C) is taken with the T3 secondary electron detector, which is positioned high up in the column and shows the surface information of the sample.
