National 416TBL-15 overview

  • 1Description

The 416TBL-15 1x/3x Stereo Microscope from National Optical is a dual magnification stereoscopic microscope fit for laboratories, high school and university students. The stereo (two) eyepiece configuration is preferred by most researchers and students because of the superior depth of field and comfort compared to monocular microscopes. This model of the 416 microscope has a paired 15x eyepiece delivering 15x and 45x magnification. The stage can be illuminated from above and/or below using a 5W fluorescent light activated by separate base-mounted On/Off switches. A fluorescent light source will not produce as much heat as a tungsten source and is also favored by many researchers for its relatively cool color temperature and long life.

A user-friendly design complements the range of features that make the 416 series a welcome addition to labs as well as classrooms. The heavy-duty post-mounted adjustable viewing head permits use of specimen heights up to 31mm (1.2"), and is also capable of 360° rotation to help share the eyepiece among colleagues and students without moving the microscope. The rack and pinion system has a single focus dial and also includes a slip clutch mechanism to prevent mishandling. An adjustable interpupillary distance, left-side diopter correction, and reticle holder/retainer provide the 416 series stereo microscope with the flexibility needed to create a customized viewing experience.
