TM-55、TM-70 series zoom stereo microscopes have biggish zoom ratio, magnification from low to high non-flash in focusing course, large depth of field, long working distance. It has many kinds of attachments. It can match with many stands and universal stands. Trinocular main body can connect CCD (COMS) camera, digital camera or film camera. Many kinds of eyepieces, divisional eyepieces and auxiliary objectives can be selected. It can match LED ring illuminator, ring fluorescent lamp, fiber etc. It can be satisfied the demands of checking up, measure and analysis in modern biology, medicine, environment, agriculture and forestry, chemistry industry, police, micro-electronics, semiconductors etc. fields. It is widely used in schools, biology engineering and science research, industry assemble, test and measure and controlling the quality.
