Low cost mid-infrared spectrometry in the field


Manufacturer of tiny, rugged, pyroelectric, mid-infrared sensors and detectors with 157 patents in sensors and ATR spectrometry, Pyreos welcomes Ocean Optics to the growing list of customers using the Pyreos family of 128-element infra-red (IR) linear arrays.

The company joins Parker Kittiwake, with its ATR Analyser which uses a similar array for testing lubrication oils in marine and other engines, and Robert Bosch, which has confirmed that it is field-trialling Pyreos-based spectrometers in India to test for adulterants in the food industry. These three global customers demonstrate the wide variety of applications for which Pyreos mid-infrared linear arrays are well suited.

The Ocean Optics MZ5 is a miniature ATR spectrometer including source, sample interface and detector, which provides a compact and fast alternative to FTIR spectroscopy. It has numerous applications including chemical discrimination, food analysis, environmental testing and scientific research.

The Parker ATR Analyser simultaneously tests Base Number (BN), Total Acid Number (TAN), insolubles, soot loading, viscosity, FAME and water content of oil samples on board a ship or in other locations, allowing all parameters to be measured using a single sample in one test kit.

The Pyreos linear arrays are optimised for these and many other applications, with 128, 128+1 (big pixel), 128+2, 255 and 510 pixels. The thin-film construction gives the arrays a very low thermal mass, which reduces their warm-up time and enables fast response times.

This reduces the spectrometers’ measurement acquisition time and increases battery life as well as end-product accuracy.

The arrays are also smaller and lower cost than functional alternatives, enabling developers to use more compact optics and modules, which widens design choices and lowers costs. This will help them disrupt existing markets and introduce high quality spectroscopy to more price-sensitive markets.

The sensor arrays are supplied with a variety of filter window options including 2.5-5.0µm (PY1499) and 5.5-11.0µm (PY0738) linear variable filters, or with anti-reflection coated silicon windows (PY0722) for broadband applications.

Andrew Wallace, CEO of Pyreos said: “We’re delighted to see our customers launching high quality devices for their chosen markets. We look forward to continuing growth in low cost mid-infrared spectrometry in the field.”
