Using the Trinocular Port The AmScope FM690T model is uniquely designed so that you can view the image through the eyepieces and the trinocular port simultaneously. This feature allows the images through the microscope’s eyepieces, and those displayed on your computer screen or television be viewed at the same time (although unless using 20x eyepieces to match your camera, the image may differ in magnification). -
