Distortion free optical lens online near-infrared spectrometer

The image cameras KUSTA1.7MSI, KUSTA1.9MSI, KUSTA2.2MSI, and KUSTA2.2MSIsens (KUSTAx. xMSI) are highly suitable for recycling applications. The undistorted optical lens ensures high spectral and spatial resolution (up to 320 adjacent measurement tracks can be measured) for measuring material flow. Due to its high frame rate, the camera can analyze and identify small particles at conveyor belt speeds of up to 3 meters per second. High spatial resolution can detect non-uniformity in complex material mixtures. These camera systems are widely used in the fields of plastic, waste paper, and construction waste recycling.

Installation settings:

The reflection of the detected object is captured by the optical lens of the camera and projected onto the InGaAs sensor array. On the line detection area, each image point (up to 320/up to 192) recorded a complete near-infrared spectrum. By performing linear scanning on objects, spatial resolution analysis of material composition can be performed. High spatial resolution can identify small components in the material flow. This camera is used in combination with PMAmsi lighting unit, installation bridge, RGB color camera, and industrial PC with control and analysis software.

Analysis and control software:

The KUSTAx.xMSI camera comes with a comprehensive set of software. The control software KustaMSI (Figure 4) allows for adjusting camera parameters and monitoring camera status. In addition to camera control options, KustaMSI also implements several standardized interfaces for transmitting data to external process control devices. Important equipment parameters are password protected and can only be changed by maintenance personnel. In addition, application routines can be modified to simplify the adaptation of hyperspectral near-infrared cameras to different sorting tasks.

LLA provides chemometric software for application development and real-time visualization of material flow
