Holmarc's tool maker's microscope model no: HO-TMRM-01 is a general purpose instrument for metrology labs. The microscope can be used for inspection as well as measurement. It is ideal for photo-lithographic labs, nano-technology labs, biomedical labs, etc.. where measurements are also required along with qualitative visual inspection.
The eye piece of this microscope is fitted with cross wire and measuring scale. The cross wire acts as a reference point for taking fine measurements. The XY stage used is of measurement grade fitted with precision micrometers with 1micron resolution. The micrometers can be either conventional engraved type or with digital display depending on the application. As the cross wire is fitted to only one eyepiece, these microscopes are monocular generally. Measurements are taken by movement of the stage. The crosswire is aligned with the first reference line or a point on the specimen or test object. Then the stage is moved watching the image to the second point on the object. Actual measurements are provided by micrometer reading. The depth can also be measured precisely using the micrometer on Z stage on which the optics head is fixed. By lowering or raising optics head, a point can be made in to focus or out of focus. By bringing the two points at different depths into focus one by one by moving the Z- micrometer, the depth can be obtained from the micrometer readings. |
