MarVision Multisensor Technology from Mahr Infinitely Adjustable Motorized Zoom Enlargement 1:10 for example with 5x lens Taking into account the tolerances to be measured it can sometimes make sense to select a measuring window and thus a field of vision that is as large as possible. This option is available with our motorized zoom. The fact that it is infinitely adjustable offers the advantage of large fields of view for alignment and high resolution with precise measurements. With the motorized zoom function motorized movement of lens groups adjusts the focal distance. This makes it easy to zoom in on the testpiece. Mechanical errors such as wobbling tilting or eccentricity of the lens group are eliminated during calibration by a sophisticated compensation function as are optical distortion and illumination changes. This compensation ensures appropriately precise and traceable measurements. The motorized zoom is available with 10x enlargement. Maximum flexibility for optical measurements Infinitely variable resolution and field of vision electronically controlled and motor-driven (1:10) A number of different front lenses can be used Can be combined with the laser sensor from front lens 5x or larger Fast video focus applicable to surfaces and at edges to measure genuine 3D points with the lens system Illumination The basic requirement for optical measurement is adequate illumination of the features for the task in hand. Three types of illumination are available and these can be used individually or combined. Coaxial incident light Vertical light for measuring 3D features Extremely powerful LED light sources for incident light Backlight This type of illumination offers the greatest contrast Reliable measurement of openings or outer edges High light intensity Telecentric design Line type design (patent pending) LED ring light Lateral illumination to increase the contrast of 3D features Independent control of all segments Simple operation thanks to anti-twist protection and stop notches at various heights Different colors are available including RGB Several irradiation angles are available Video Filter Two kinds of video filters have been developed to obtain reproducible geometric elements from the video image The geometry filter eliminates all image points no longer belonging to the required geometry e.g. radius transitions on straight lines. Unwanted soiling burring or splash effects at the edges are identified by the speckle filter and excluded from the measuring result. In both cases the measurement is very stable and independent of the operator. Geometry filter Speckle filter
