Diffuse Reflectance (NIR) Spectrophotometer - i-Spec Plus

The i-Spec Plus is a diffuse reflectance near-infrared spectrophotometer platform with a built-in integrating sphere and tablet PC, making it ideal for customers to develop mobile applications. The large spot size and optional rotating sample turntable provide more representative sampling for large and heterogeneous samples.

Models developed in B&WTEK’s chemometric software may be transferred to onboard software (BWSpec®Mobile) for NIR analysis anywhere, especially when combined with the battery pack option. It is also possible to connect the i-Spec Plus spectrophotometer to a PC in order to utilize further data processing power with B&W Tek's proprietary BWSpec software, and also for model-building with BWIQ.

SDKs can be used for system control, allowing OEMs to produce custom interfaces. Communication via Bluetooth and Wi-Fi is available on the tablet PC.


The key applications of the i-Spec Plus are as follows:

  • Edible oil
  • Food counterfeiting
  • Agriculture: fruit, fertilizers, leaves
  • Forage and feed (moisture, protein, and fat)
  • Plastics and carpet recycling
  • Fibers and textiles


The key features of the i-Spec Plus include:

  • Various data format options available
  • Press-holder and optional turntable sample stage
  • Touchscreen operation or external computer
  • Portable rugged all-in-one design
