National Optical Dual View LED Microscope

The Dual View LED Microscope from National Optical has a dual head and is designed for use through grade 12. Defining the scope from other similar models, however, would be its cool running built-in LED illumination, which provides light with a bulb rated at 50,000 hours. This bulb is brighter than a standard 20W tungsten, and gives off virtually no base heat.

The dual head design makes it ideal for sharing in the classroom, and both the vertical and diagonal viewing tubes feature widefield 10x eyepieces with revolving pointers. The vertical tube is inclined 30° for more ergonomic viewing, and both tubes rotate 360°, thanks to the rotating head.

The viewing tubes lead to the 3 DIN standard, achromatic, parfocalled, parcentered, and color-coded objective lenses. The lenses are 4x, 10x, and 40xR times, providing students with an array of choices for accurate specimen viewing. The objectives look down onto the movable stage, remaining fixed to prevent damage to the specimen slides or lenses. The tension adjustment also eliminates stage drift. Separate low position coarse and fine focusing controls enable students to see specimens, and the slip clutch prevents damage to the focusing system.
