The Dino-Lite Premier AM5116ZTL is a VGA connection microscope with polarizer and enhanced working distance that connects directly to computer monitors or TV with VGA (DE15, D-SUB) input for a resolution of 1024 x 768. Simply plug a standard VGA cable into the VGA adapter on the microscope cord and plug directly into your computer monitor. This model has a range of 20x - 90x magnification with longer working distance from your subject and provides real time imaging at 30fps. The adjustable polarizer is designed to reduce the effects of glare and to help eliminate “hot spots” from highly reflective surfaces and providing uniform illumination to bring out more surface detail with minimal glare. The new sensor provides enhanced low light visibility for clear images in any situation. The AM5116ZTL has the capability to freeze the live video to examine details with a simple tap of its MicroTouch. The LEDs can also be switched by tap and holding the same MicroTouch for two seconds.
