Megatrend of “well-being”:

Consumers want to know what‘s in their food

Mobile spectroscopy required !

OSRAM OS as technology leader for

innovative light sources

Spectroscopy enables material identification with the

creation of a wavelength fingerprint

How does it work?

1 Scan the molecular makeup of an object,

like an apple

2 The device creates a spectrum specific to the

object (wavelength fingerprint)

3 This spectrum is then analyzed in a cloud Cloud

What could it be used for?

• Vegetables & Fruit: Water content, carbs, calories

• Dairy products: Calories, fat, proteins, water

• Bodyfat

• Medication validation

… and much much more

The world’s first infrared spectroscopy lab:

Empower consumers to check what is in their food

Enabled by OSRAM’s broadband infrared LED “SFH 4735”

The first NIR broadband LED on the market!
