Hispim

Overview

A novel and cost-effective system for the real-time identification of ceramic-glass and glass-like contaminants.
The technical approach is based on the infrared analysis of glass and ceramic-glass spectra with a PGP (Prism-Grating-Prism) spectrographic optics. The use of an infrared array allows reduced measurement times and simultaneous measurements on wide linear areas with high spatial resolution. This new technology increases accuracy and efficiency and allows the detection of transparent glass-like contaminants.
The basic system architecture of the HISPIM system is composed by a spectral imaging detection system including the spectrographic device (lens, PGP spectrograph, CMOS camera) capable of acquiring the spectral images of the cullet, the elaboration system (frame grabber, industrial PC, optionally DSP board) and an automatic spectrometer calibration device.
The spectral imaging detection system is used to detect the position of the cullet and, in real time, commands an air-jet sorting sub-system to blow the cullet from off its normal falling line.

Features
