Microspectroscopy of larger samples

The QDS III™ is the third generation of the worlds only minispectrophotometer.  It is designed for larger scale microspectral analysis of gemstones, documents, currency, circuit boards, semiconductor, flat panel displays and optical components.

The QDS III™ minispectrophotometer is designed to simplify the objective analysis of color and fluorescence of questioned documents, minerals and  samples too large for a conventional microspectrometer.  The minispectrometer is rugged and easy to use and includes long-life light sources, an integrated spectrophotometer, secure computers, and easy to use software. The minispectrometer also includes high-resolution, color digital imaging...up to 6 megapixels! All these features, along with technical support, are included with the QDS III™ minispectrophotometer.
The QDI QDS III™ minispectrometer can be configured to acquire spectra from the near ultraviolet to near infrared. It can be added to a stereomicroscope and machine vision systems to acquire spectra and images in absorbance, reflectance, polarization and fluorescence.  The lit hexagonal optical head is a trademark of CRAIC Technologies, Inc.
