The tec5USA Distance Measurement Head is designed for measurements over large distances, such as samples on a conveyer belt. The variable working distance allows for measurements in close and far proximity to the sample, with an irradiation spot size of ~22 mm. The high protection class and scratch-resistant optics permit the measurement head to be integrated into harsh industrial environments. The measurement head illuminates the sample with a 45°/0° angle configuration and contains a long-life halogen light source to guarantee device reliability.
For food, feed, and agricultural production facilities, tec5USA’s over-belt Distance Measurement Head includes a NIR and/or Visible spectrometer in an IP69 stainless steel housing. This ingress protection withstands the dust, high-pressure water, and chemicals experienced in cleaning and wash-down cycles.  The NIR spectrometer wavelength range is 1000-1700 nm or can be expanded to 1000-2200 nm. A visible spectrometer (300-780 nm) can be used as a standalone system to measure color or combined with a NIR spectrometer to create a multifaceted and high-performing system to generate chemical, quality, and color data simultaneously within seconds.
