Overview

High Speed, High Density 3D Web scanning Measurements together with fully synchronized high density color vision for web scanning applications. Coplanar laser dots achieve a narrow scan zone. The chroma+scan 3350 family is modular where multiple sensors are combined to match the width of the web. Additionally, these sensors can be mounted above and below the web material to measure the true differential thickness top / bottom. The chroma+scan 3350 has the 3D profiling of the 3150 with the addition of full color measurement with a pixel resolution of 1mm x 0.5mm.

Features

Coplanar Scanning

All laser points are in line, or coplanar. This provides all data in the same scan plane during measurement with no requirement to realign data which is important in data registration of web applications. A single plane also results in a very narrow scan zone making it easier for installation.

True Differential Scanning

Coplanar scanning also allow for the true differential scanning where the upper and lower rows of lasers are in the same plane. This makes the thickness profiles extremely accurate and most important not subject to errors caused by material vibration in situation where the top and bottom scan planes are offset in the direction of travel.

Colour Vision

The chroma+scan adds full colour vision at a density of 1mm x 1mm resolution (direction of travel) to the 3D scan data. An added feature is that the pixels are adjusted to match the 3D profiles. This means that the registration of the colour image matches the variations in the surface profiles and removes any error caused by the surface distance from the sensor.

Factory Calibrated, Linearized and Temperature Compensated

Each sensor is fully calibrated and linearized in our factory on precision benches. This means that the sensors can be mounted onto your scan frame and all that is required is a simple reference process of passing a target of known dimension through the sensors to establish what the real world coordinate offsets are. This ensures that your system will operate optimally from head to head and systems to system. This also eliminates the tedious process of field calibration and the variations that can occur. Additionally, the sensors are temperature compensated over their full operating range to ensure the linearity is maintained.

Industrial Enclosures

These sensors are IP67 and designed for industrial applications in harsh environments. These are purpose built and go well beyond sensors that are designed for lab only or controlled environments.
