Optical detection spectroscopy system NIR

Overview

• On-line, continuous, real-time, contactless measurement on a conveyor belt.
• Designed to improve yield and quality control in industrial processes; reduces energy and raw material use — quick ROI.

Measured constituents / Applications

• Humidity
• Fat
• Protein
• Collagen

Advantages
Simultaneous measurement of two constituents using near-infrared absorption spectroscopy. Contactless, fast and continuous measurements (up to 1 measurement every 33 ms). Measurement spot up to 70 mm.

• Insensitive to granulometry, color, height variations and ambient light.
• Easy to install and configure.
• Optical cleaning by air blowing system.
• Automatic product presence detection.
• Optional LED source (NIRLED) with very long lifetime.
• Stand-alone sensor for simple integration.
• Low cost with rapid return on investment (typically < 1 year).

Working principle
The system operates by near-infrared absorption spectroscopy: an infrared source illuminates the sample through interferential filters selecting useful wavelengths. Backscattered light is collected by a parabolic mirror and focused on a detector. The constituent content is deduced by analyzing measured spectral values and applying calibration models.
