601984 series high-contrasted coaxial illumination zoom monocular video microscopes have two types, 601984BC(binocular) and 601984BTC(trinocular). They are the high-class products within coaxial illumination microscopes. Original imaging and illumination optical system design, making it have higher contrast and depth of field, are finished video displaying and binocular eyepieces observing at the same time，The image is erecting by eyepieces observing. It can be used in observing and checking-up reflecting objects. Specially fit for checking-up LCD, plane pressworks and other plane articles with low reflectivity.
