MicroNIR Pro

An ultra-compact, general-purpose spectrometer

The MicroNIR™ Pro is an excellent development tool for a new user assessing the feasibility of NIR spectroscopy for their applications. The product is offered with a number of accessories that allow for ease of use in an at-line or laboratory setting.

Viavi’s MicroNIR Pro 1700 ES is a lightweight and cost-effective near infrared (NIR) spectrometer that includes Viavi’s high-precision optical coating technology with innovation in optical system design and miniaturization.

By combining Viavi linear variable filter (LVF) technology as the dispersing element, the spectrometer has a light source, collection optics, electronics, and LVF in a housing that measures <50 mm in diameter, <45 mm in height and weighs only 64 g. The spectrometer is USB powered and can be used in diffuse reflection, transmission, or transflection modes. A MicroNIR Pro package includes a number of accessories that either enhance ease-of-use or enable measuring with varied configurations that perfectly suit specific applications.

Standard Accessories

MicroNIR Pro Case
  • Standard collar for normal operation
  • Vial holder with 100 5 ml glass vials
  • Windowed collar for powder and soft material measurement and easy cleaning
  • 99% spectralon references for vial measurement and point-and-shoot operation
  • Softshell case for transportation and shipping
  • Bracket with ¼-20 thread for ease of mounting on regular optical post or mount

Options

  • Transmission fixture for liquid sample measurement

Key Benefits

  • Covers the first and second overtone spectral region: 950 – 1650 nm
  • Powerful calibration model development tool
  • Enhanced electronic and mechanical design for better system stability and thermal control
  • Real-time predictions and method management

Applications

  • Food, feed and agriculture
  • Pharmaceutical
  • Industrial processing

Software

The MicroNIR Pro ES 1700 comprises of user management, data acquisition, method development and real-time prediction software. Within the model development software, a developer can perform spectral data pre-treatments with a comprehensive package of industry-standard tools such as smoothing, derivatives, and baseline corrections. Tools enabling 21 CFR part 11 and instrument performance qualification per USP 1119 test criteria are available. Embedded calibration development software powered by CAMO Software’s The Unscrambler® X provides classification and regression algorithms and a complete set of chemometric tools for calibration model development and data analysis. The MicroNIR Pro Lite version does not come with the embedded calibration development software, but it is well-matched with CAMO Software’s Unscrambler X (version 10 or higher).
