3.1.2 Replacing the projection lens
This projector has adopted the fixed focus lens to 10X to 100X.
When replacing the projection lens in order to change the magnification, it is required to
switch the condenser lens according to the magnification of projection lens.
3.2 Mounting the Workpiece
Mount a workpiece on the stage glass or use a fixture or a jig to hold it in position. Use the
T-grooves for securing fixtures and jigs to the cross-travel stage.
TIP
The surface or contour to be projected must face the projection lens. Position the surface
to be measured so that it is normal to the optical axis of the projection lens.
