Features 1.10 million pixels image of CMOS, ensure the bacteriostatic circle high-definition digital imaging. 2.three color LED mixed light source to replace the traditional cold cathode fluorescent lamp, energy saving 80%;Life 100000 hours, no stroboscopic, no radiation, no mercury, more environmentally friendly. 3."suspension" dark field system can make the transparent bacteriostatic ring and the white fungus to black and white, high contrast, increase the sharpness of the image. 4.multimodal bacteriostatic circle measurement, to adapt to the bacteriostatic circle clear, rupture, fuzzy and other conditions. Technical parameter 1. The imaging system 1) image sensor: 10 million pixels CMOS, true color 2) optical lens: 8 mm F / 1.4, high precision, high fidelity, distortion < 1% 3) image environment: fully enclosed, without interference, automatic center, the "black sun 4) built-in light source: three color LED mixed soft light, floating dark field camera system (fast patent) 2. The bacteriostatic circle measurement model 1) automatic detection: the bacteriostatic circle outline based on the accurate edge detection, edge is clear, standard circular bacteriostatic ring 2) quasi circular approximation: based on the bacteriostatic circle circle fitting approximation contour, suitable for broken edge, non-standard bacteriostatic circle round 3) artificial detection: the mouse to click the bacteriostatic circle round edge on three, is suitable for the bacteriostatic circle edge blur 3. The determination of antibiotic titer 1) titer test (1) : a dose method is suitable for the United States pharmacopoeia 2) titer test (2) : a dose method is suitable for the United States pharmacopoeia 3) the second dose titer detection: suitable for the Chinese pharmacopoeia 2010 edition 4) three doses titer detection: suitable for the Chinese pharmacopoeia 2010 edition 5) the combined inspection: suitable for the Chinese pharmacopoeia 2010 edition 4. Precision instrument 1) repetitive testing relative error of 0.01% or less, the repeated measurement accuracy of 0.002 mm or less 2) uniformity self-checking: the relative error of 0.05% or less 3) titer measurement accuracy of 0.3% or less 4) titer repeated measurement accuracy of 0.3% or less 5) measure the difference between 0.2% or less
