MIC TMM-490 series high-contrasted coaxial illumination zoom monocular video microscopes have two types, TMM-490BC(binocular) and TMM-490BTC (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 presswork’s and other plane articles with low reflectivity.
Main technology Specifications：
It can be finished video displaying and eyepieces observing at the same time. The orientation of the observing image and the object is the same. The image is erecting. Choose to buy corresponding adapter, can connect CCD (CMOS) camera, digital camera or film camera. · Standard eyepieces observing total magnification is 14X~90X. 1.4X~9X zoom magnification body, WFH10X/22 plane eyepieces. The working distance is103mm. Matching 2X auxiliary objective and 30X eyepieces, the maximal magnification is 540X.· Long life, environmental protection type many kinds of wavelength high lightness LED coaxial illuminator · Binocular eye tubes inclined 45°· The range of adjusting the diopter is ±6· Interpupillary distance adjustment range 53~75mm· The range of adjusting focus: Hand wheel adjusting focus is50mm. The height of round post is242mm.· The measurement to match between the support and the main body is Φ45mm. · WFH10X/22、SWF15X、SWF20X、SWF30X four kinds magnification eyepieces and 0.7X、2X auxiliary objectives to be matched.· There are 0.3X, 0.5X, 1X CCD adapters to be matched.
Main advantages: its high contract and high definition are the same level to the other international similar competitive grade, but the price is less than those products. The image is erecting, TMM-490BTC are available for binocular and trinocular. It can see including LCD, chips, wafer etc. almost the whole objects. Main sphere of application: it uses to observe, analysis and checking-up wafer fab, chips, LCD etc fine test with low reflectivity and generic objects high clearly imaging observing, analyze. Especially fit for the high level research.
