Haag Streit AT 870 Applanation Tonometer

The AT 870 is mounted permanently on top of the slit lamp microscope. The feeler arm protrudes from above into the beam path of the microscope and illumination unit.  If the feeler arm is swivelled into the park position, the slit lamp can be used immediately for the examination. The applanated surface is observed monocularly through the left eyepiece of the stereo microscope.
