Near-infrared spectroscopy

Mega Trend – Wellbeing?

Consumers want to know what‘s in their food

Mobile spectroscopy required!

OSRAM Opto Semiconductors is expanding the product portfolio for Near-Infrared Spectroscopy. Near-infrared spectroscopy enables such things as the water, fat, sugar and protein content of food to be measured. This technology uses the characteristic absorption behavior of certain molecular compounds.

Technology

How does it work?

Near-infrared spectroscopy enables such things as the water, fat, sugar and protein content of food to be measured. This technology uses the characteristic absorption behavior of certain molecular compounds. If a defined light spectrum is directed at a sample it is possible to determine the presence and quantity of certain ingredients from the wavelength distribution of the reflected light. An IRED, such as the
SFH 4735 or SFH 4776, acts as a compact light source for the spectrometer.

  • Scan the molecular makeup of an object, like an apple
  • The device creates a spectrum specific to the object (wavelength fingerprint)
  • This spectrum is then analyzes with the help of a database

Advantages

The basis of the SFH 4735 and SFH 4776 is a blue 1 mm² chip in UX:3 technology. Its light is converted into infrared radiation with the aid of a phosphor converter developed specifically for this application. A residual blue component in the light helps users target the area they want to investigate. The emission spectrum of the SFH 4735 and SFH 4776 has a homogeneous spectral distribution in the infrared range from 650 nm to 1050 nm. They are the first and only LEDs on the market with this broad spectral range in the near infrared regime.

The SFH 4735 is the proven and compact OSLON® Black Flat, where the package is characterized in particular by good thermal resistance.

By making improvements to the phosphor material and technology, developers at Osram Opto Semiconductors have succeeded in increasing the intensity of the light by an impressive 60 percent compared with the predecessor component. The SFH 4776 with the tiny and robust SYNIOS® P2720 package shows this impressive intensity improvement. For the customer this means an improved signal-to-noise ratio and therefore simpler analysis of food and medicines. The small package size qualifies the SFH 4776 to be integrated into space restricted applications, such as smartphones. OSRAM can support with application know-how and is #1 for NIR emitters. OSRAMs knowledge, network and partnerships help to accelerate the application development.
