This microscope features a unique simile-focal optical system with an adjustable trinocular port to enable well-focused, clear images on your computer/video screen while simultaneously obtaining sharp, focused images through the eyepieces. Other trinocular microscopes may allow viewing through a photo-port at the cost of losing an eyepiece through switched-viewing. By sharing an optical pathway, this microscopes photo-port works concurrent with both eyepieces. Especially convenient for quality-control inspections, teaching-demonstrations, and many other industry-applications, your colleagues or students can simultaneously view clear images shown through the trinocular port while you work through the eyepieces. The 45-degree incline and high-eye point design ensures comfortable observation, including the use of eyeglass or goggles.
