Measuring projector objective/positive projector objective

Measurement of Projector Objective Lens - Introduction

Projector objectives are widely used in industrial measurement projectors.



Projector Objective - Working Principle

The tested workpiece Y is placed on the digital projector worktable. Under the illumination of transmission or reflection, the tested workpiece is magnified by the objective lens 0 to form a real image Y '(inverted image) and reflected by the light mirrors M1 and M2 onto the sanding surface of the projection screen P. The workpiece is magnified and imaged onto a projection screen through an objective lens, and the contour of the workpiece on the projection screen is measured using a digital measurement system (consisting of an electronic ruler and a DC-3000 or QC200 data processor) on the workbench; The angle of the workpiece contour can also be measured using a projection screen rotation angle digital display system.



Projector Objective - Classification

Positive projector objective, reverse projector objective, horizontal projector objective



Projector Objective - Magnification Classification

5X、10X、20X、50X、100X， The objective lenses between the measuring projectors can be interchanged freely, and the magnification error of the objective lenses is ≤ 0.08%.
