Used AMERICAN OPTICAL 568 #293744911 for sale

AMERICAN OPTICAL 568 is a popular compound wide-field microscope, designed for general laboratory use. It is a culmination of improvisations from the original AMERICAN OPTICAL Model 451 microscope, featuring a Kohler illumination equipment, offset optical path and built-in illuminator. 568 has a wide 550mm (21.6in) field width with a maximum power of 40x. It has a monocular viewing position, with 10x eyepiece to give a viewing mode of 400x. It's equipped with a trinocular port to accommodate an optional camera, video setup or other optical device. The optics system consists of achromat infinity optics, corrected color imaging, and adjustable parlant focusing. The parlant focusing moves the objective lens along the optical path to provide an image quality that is unrivaled and free from astigmatism and chromatic aberrations - a feature that is shared among many of AMERICAN OPTICAL microscopes. AMERICAN OPTICAL 568 has a patented Cohler unit of illumination that provides a uniform, adjustable light field over the entire viewing area and can hold three bulb wattage (20, 33 and 50W). The Kohler Illuminator has a light reflector that directs light across the diaphragm, providing illumination to areas with poor light transmittance, i.e. darkfield, polarized or phase contrast. The stand of 568 features a rough precision metal cast, which is replaceable and offers very little shifting of the objectives and eyepieces. The movement is smooth and accurate due to finely threaded adjustable screws that allow appropriate placement of the lenses. AMERICAN OPTICAL 568 is an outstanding microscope for general use, giving outstanding clarity and a good contrast. The Kohler machine of illumination is especially helpful to obtain, clear and enhanced visuals in subtle light. It is a reliable, powerful and long lasting lab microscope, which will serve for a longer time if well maintained.
