Microspectra 121 Forensic™ Microspectrophotometer

The Microspectra 121 Forensic™ microspectrometer is designed for forensic analysis. It incorporates the latest technological advances in optics, spectroscopy and software to deliver the best performance microspectroscopy of trace evidence and questioned documents. It is easy to use yet able to non-destructively spectrally analyze features ranging from sub-micron to over a 100 microns across. As such, the Microspectra 121 Forensic™ represents a giant leap forward in forensic microspectroscopy and document examination.

The Microspectra 121 Forensic™ microspectrophotometer combines the latest technologies to allow the user to measure UV-visible-NIR range transmission, absorbance, reflectance and fluorescence spectra of samples as small as one micron. And all with the same instrument! Additionally, the samples are viewed simultaneously during microspectral data acquisition. This allows the user to visually and spectroscopically locate and analyze their evidence.

The Microspectra 121 Forensic™ microspectrophotometer is simple to use, the measurements are non-destructive and the spectral data is unmatched.



The Microspectra 121 Forensic™ Microspectrometer can take spectra and images from the deep ultraviolet to near infrared with one seamless operation. It can acquire microspectra and images in absorbance, reflectance, and fluorescence. The microspectrometer is offered with both the DirecVu™ to view samples by eye as well as with a high resolution UV-visible-NIR digital imaging system. Manual and automated configurations are available as are such options as hotstages. The lit blue base and lit hexagonal optical head are both trademarks of CRAIC Technologies, Inc.
