Traditional microscopes on the market give you the ability to see through either the trinocular port forcing you, Or eyepieces to switch between the port and eyepieces. Because their trinocular port is not crafted to serve as simul, Focal with the microscope optical system, You have to conduct re, Focusing after each switch . The t580a, However, Has simultaneous viewing and simul, Focal trinocular port so that these switch and re, Focusing are no longer necessary. Especially handy for clinical examinations, Teaching demonstrations and these features, Laboratory applications allow your students or colleagues to view crystal clear images simultaneously while you work through the eyepieces.
