The bilateral telecentric lenses for matrix and linescan cameras set a new standard of lens performance for optical metrology. The absolute distortion in the image plane of these lenses is only a few micrometers.
The lenses can be focussed on the image side in a range of +/- 3mm which means that the working distance can be adjusted within the defined limits without any change in the lens magnification. Thus the lenses can easily be adjusted to fit the space conditions in the application. Due to the numeric aperture of 0.14 or 0.13, the light intensity of these lenses is considerably higher than of other available lenses. The integrated iris allows easy setting and locking for the demands of any measurement task.
