Portable, battery-operated smart spectrometer. It covers many field applications and its configuration is optimized for diffuse reflectance, transmission and fiber input detection for spectral range between 900 nm and 1,700 nm. 99% of food is made of proteins, carbohydrates, fats and water. NIR provides a means for measuring these components in food. The NIRvascan™ is the first world portable smart and affordable near infrared spectrometer with integrated tungsten halogen light source build in. It covers many field applications and its configuration is optimized for diffuse reflectance, transmission and fiber input detection.The NIRvascan™ smart spectrometer is already setup to be used with most Android or iOS devices with Bluetooth, as well as with any computer running on Windows. With the touch of a finger, you can can now have extensive information on the NIR spectrum of any substance. The data can easily updated to a computer for more complex tasks.
