Product description The 453TBL-15-LED 2x/4x Stereo Microscope from National Optical is a dual magnification stereoscopic microscope designed 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 453 stereo microscope has a paired 15x eyepiece delivering 30x and 60x magnification. Two achromatic paired objectives are parcentered and parfocalled to keep the specimen centered and focused when switching between the two magnification settings.The 453TBL-15-LED microscope can illuminate specimens from above and/or below using cordless LED lights activated by separate base-mounted On/Off switches. LED lighting is suitable for microscopy because of its cool operating temperature, relatively white color temperature, and energy efficiency. The cordless LED lights will provide up to 50 hours of illumination after a full eight-hour charge. The rack and pinion system has a single focus dial and includes a slip clutch mechanism to prevent mishandling. An adjustable interpupillary distance, left-side diopter correction, and reticle holder/retainer make the 453 stereo microscope a welcome addition to classrooms as well as labs. - Optical System
