The Nikon Optiphot 66 is a reflected-light microscope designed for industrial use to view materials such as metals, semiconductors, and other material samples. The Nikon Optiphot 66 provides brightfield and darkfield reflected-light illumination settings with 5x, 10x, 20x, and 50x objective lenses. The Nikon Optiphot 66 uses a halogen light source and offers a large XY stage for larger sample sizes.[1]
What it is
The Nikon Optiphot 66 is a reflected-light microscope designed for industrial materials inspection. The Optiphot 66 is offered with either a binocular or trinocular viewing head that is 360-degree rotatable. The microscope is intended for viewing metals, semiconductors, and other material samples.[1]
How it works
The Optiphot 66 uses a reflected light illuminator that provides brightfield and darkfield illumination settings. A quadruple nosepiece holds objectives. The objectives supplied are brightfield/darkfield 5x, 10x, 20x, and 50x lenses. The microscope employs coaxial coarse and fine focusing. A halogen light source is used. The stage is a large XY stage.[1]
