The Brandeis seal as imaged when projected onto a glass slide through various microscope objectives. In each case, the image was taken twice, once onto a clean glass slide (shown here) and once onto a 100-μm grid for measurement (not shown). Top left: The image being projected. The scale bars in the images above are: ×2 objective, 1-mm scale bar; ×4 objective, 500-μm scale bar; ×10 objective, 100-μm scale bar; ×20 objective, 50-μm scale bar; and ×40 objective, 20-μm scale bar.
