Adding a Scale Bar to Images Taken with the Leica Fluorescent MicroscopeUsing Built in Software (Leica Application Suite) –more convenient for a couple imagesTake an image –Aquire tab -> Acquire ImageSwitch to Process tabSelect your image from the dashboard at the bottom of the screenSwitch to “Calib.” Sub-tabClick “Manual (Draw Line)”Enter the “pixels” and “length” for the objective you used according to the chart below:Select microns as the unitClick “Apply”Switch to “Annotate” sub-tabIn the Scale Bar tab, click “Show”You can now click and drag the scale bar to place it wherever you pleaseYou may also change the length by selecting “User Length” and typing a new valueFormat the font and colors in the “font” boxIn the “Actions” box, click “Merge”Right click on the large image, click “Save As”Save the image with scale bar to you folder.Using ImageJ –Easier for many imagesSave all images with the magnification in the name or on the folder!!!(ex: 5x, 10x...)Download ImageJ: http://rsb.info.nih.gov/ij/download.htmlInstall ImageJOpen the first picture file into ImageJ: ctrl+O (or) file -> openSet Scale: Analyze -> Set Scale...Enter pixel and distance values and unit of length according to table below:Lens MagnificationDistance in PixelsKnown DistanceUnit of LengthLeica 5x107200μmLens MagnificationPixelsLengthUnit of LengthLeica 5x107200μmLeica 10x107100μmLeica 20x438200μmLeica 40x431100μmLeica 63x680100μm
