Easson Factory High Accuracy Optical Measurement Inspection System Profile Projector
Product Description
EP series Optical Profile Projector operating principle
A work piece Y is placed on the table surface, there is an parallel ray illumination system S1 in below the work piece, the light from lamp S1 is made to be a parallel ray by the optical system K1 & C1, then the image of the work piece Y is precisely projected to a precision magnification lens O, the image then reflects through two flat mirror M1 and M2, finally projected to the screen P and become a magnified image Y'.
Since the magnified image Y' is highly precise in dimensions, operator can measure the magnified image Y' by a glass grating scale to know the dimensions of the workpiece Y.
EP series profile project equipped with a high precision digital readout system in the XY table which enable operator direct readout the dimension of the work piece with the assistance of magnified image.

Robust friction transmission system
To avoid the usual backlash problem of normal lead screw transmission system, rod base friction transmission system are used in the XY movements. This solution provides excellently smooth, sensitive and backlash free positioning that assure easy and precise measurements.
High precision linear guideway
high precision linear guideways are used in all X, Y and Z axis movements. This design provides very high straghtness movements and consequently, high measurement accuracy.
High stability machine casting
To avoid deformation caused by the internal stress of the metal casting, in addition to the usual internal stress release process ( by tempering ), all EP-1 casting are further stress released by a computer controlled vibration stress release. This process assure high dimensional stability and long lasting measuring accuracy.
