To extend our vision in low light, night vision goggles use image intensifiers and optics to amplify NIR wavelengths. As this application note demonstrates, measuring transmission filters used in night vision devices benefits from the use of a high-sensitivity spectrometer.

Olive oil production is a multibillion industry, with food-grade varieties subject to regulation regarding their origin and quality. In this application note, the Ocean Optics Spark spectral sensor identifies potentially damaging adulterants and dilutions in olive oil samples.

With the use of a new generation of robust, repeatable and stable instrumentation, manufacturers can more easily assess sample quality under rigorous conditions. In this application note, we investigate the thermal stability of a spectrometer system for process line transmission measurements at different temperatures.

In this application note, we measured the absorbance of a nutrient-dense juice blend comprising acai berries and other fruits.

Plastic tubing is available in a variety of opacities ranging from clear to translucent. The transparency of plastic tubing varies for reasons such as providing contrast for visual monitoring of fluid flow, decreasing exposure to ambient light, and making the tubing more distinct for machine vision technology. Visible-NIR transmission spectroscopy is used to assess the amount of frosting applied to plastic tubing to determine if the tubing meets the required opacity level.

In this Application Note, we show the impact of stray light on absorbance levels and describe how optimizing the choice of light source can minimize stray light and increase the maximum absorbance measured.
