Glass-Scanner I-Mike

Glass-Scanner I-Mike (model 1102)

Overview

I-Mike provides contact free measurements of the relevant parameters of transparent objects (tubes, rods, bottles…).

Within each measurement interval the transmitter scans the measurement field by moving a laser beam exactly parallel to the optical axis. Located behind the measurement object, the receiver is facing the transmitter. He detects the incoming beams aside and through the object. The diameter and position of the object is calculated by evaluation of the object's shadow.

Wall thickness or inner diameter of transparent tubes is measured by evaluation of the beam paths through the object. In the case of glass rods, the refraction index and two diameters are measurable (parallel and perpendicular to the optical axis).


Application Fields

Control

Precise measurements during production (even if the objects are still hot) allow significant improvement of production quality. In various processes either a reduction of product tolerances and a minimisation of waste production was achieved.

Quality Management

The software (IMD) provides full functionality for the generation of tube inspection protocols. These include (besides diameters and wall thickness) Siding, Ovality and Bow Measurements.

Volumetric Analysis

By the use of inner diameter measurements over tube length it is possible to calculate the included volume. The usual filling of tubes is not necessary.
