 Precise Focus Indicator Assures Accurate Z-Axis Measurements |
 Non-Contact Measuring Microscope The DMM3000 Allows Precise, Repeatable and Accurate Depth Measurements Without Physical Contact - Even on Difficult Samples |
This indicator enables even inexperienced operators to focus accurately on reflectivity surfaces, regardless of any visible structure. Measurement of the Z-axis are achieved by first focusing accurately on the top of the relevant feature to be measured and then refocusing on the bottom. The true point of focus is reached when the two halves of the PFI coincide. The movement in Z-axis in refocusing is the required thickness or depth on the digital readout unit.
Readout resolution allows for a precision of 1 micron.
Advantages? Non-contact measurement method prevents any physical damage to delicate samples.
