UV/VIS/NIR microspectrophotometry


CRAIC Technologies, in collaboration with the best professionals in the industry, has developed the innovative series of QDI (Quantum Detection Instrument) Microspectrophotometers. 

The instrument is designed to acquire spectra on microscopic samples (or microscopic parts of them) in a non-destructive fashion and without coming into contact with the sample.

CRAIC's revolutionary Microscope /UV/VIS/NIR Spectrophotometer, allows for spectra between 200 and 2100 nm to be obtained in a sample area of ​​1 micron.

The software can be customised according to user requirements.


CRAIC ™ Lightswitch is an optical multiplexer or switch designed to add more functionality to a microscope. This device, once connected to an optical opening on the microscope, can handle the additional functionality, including UV-visible-NIR spectroscopy, image analysis, Raman spectroscopy, refraction index measurements, and much more.


The CRAIC Range includes:

  • 20/30 PV ™ UV/VIS Microspectrophotometer
  • 20/30 XL ™ UV/VIS Microspectrophotometer for large scale samples
  • Felx ™ Modular Microspectrophotometry for maximum flexibility
  • 508 PV ™spectrophotometric module Microspectrophotometry
  • Elixir ™ Microspectrophotometry for forensic analysis; it incorporates superior optics, a high quality spectrometer, high-resolution digital imaging and advanced software ... uses the most innovative Lightswitch technology by CRAIC ™
  • Apollo ™ Raman Microscope for Micro-Raman analysis
  • UVM-1 ™ Microscope dedicated to analyses in UV, range extended for VIS
  • MP-2 ™ spectroscopic module and image analysis for microscopy
  • Coal Pro II ™ Microspectrophotometry for organic petrographic analysis using ISO 7404-5 and ASTM D2798 methods.
  • RIQ ™ is designed to measure the index of refraction of microscopic glass fragments. IRQ ™ (Quantification Index of Refraction) complies with ASTM E 1967 method

20/30 PV ™ UV/VIS/NIR Microspectrophotometer

The new generation of QDI 2010 ™ microspectrophotometer represents the latest technology in microspectrophotometry.

Its potential allows for the acquisition of spectra in transmission, reflection, polarisation and fluorescence, on microscopically small samples, starting from deep ultraviolet up to the near infrared with great ease, speed, and a very high resolution.

QDI 508 PV ™ Spectrophotometer-Microscope

The QDI 302 ™ is the combination of microscope and spectrophotometer and was designed to add the potential of a spectrophotometer to an optical microscope or to update an old microspectrophotometer.

It can acquire spectra in transmission, reflection, and polarisation of fluorescence on microscopic sized samples starting from the deep ultraviolet up to the near infrared, in addition to carrying out single wavelength measurements.

QDI QDS III ™ Stereomicroscope ™

The QDI QDS III ™ is the first StereoMicrospectrophotometer in the world.

The QDS III ™ is designed for the micro-analysis of inks, paper, minerals, electrical circuits, in addition to larger and more heterogeneous materials by measuring reflectance, transmission and fluorescence from deep ultraviolet to near infrared.


The QDI 2010 ™ microspectrophotometer is the most advanced ever built.

Thanks to the latest available manufacturing technologies, the QDI 2010 was an extremely powerful tool in non-destructive analysis in microscopy, while at the same time being very easy to use.

The samples below 1 micron can be analysed very quickly and with a minimum of sample preparation.

The microspectrophotometer can measure the microspectrum of a sample in transmission, reflection, polarisation and fluorescence in the near-UV region, visible and near infrared NIR with a very high spectral resolution, all with a single instrument and without having to change its configuration.

Thanks to the DirecVu ™ package, samples can also be observed through the eyepieces.

The instrument's working range is worth mentioning:

  • UV: Measuring range expanded to deep UV
  • VIS: Region of complete visibility
  • NIR: Microspectroscopy in near infra-red.
  • Other distinctive features include:
  • A single microspectrophotometer with a TE Diode Array detector integrated and cooled to reduce noise and increase stability over time
  • Instant browsing in a single operation without any changes in the optics in the UV / Visible and NIR measuring field
  • Readings in transmission, reflection, fluorescence and polarisation of microscopic samples
  • Technical and application support.
