CRAIC Technologies™ offers both polarizers and analyzers with a UV-visible-NIR spectral range.  Designed for spectroscopy and imaging applications, these polarizers and analyzers are fitted into custom holders that are designed to protect the optical component as well as to fit smoothly and easily into the optical path of the CRAIC Technologies instrument.  Both rotating and fixed polarizers and analyzers are available and can be supplied either individually or as sets, depending upon your requirements.

WIth a spectral range from the deep UV to the near IR, CRAIC Technologies polarizers are available both for transmission and incident illumination optical paths.


Polarization Microspectroscopy

Spectroscopy of birefringent samples

Polarization microspectroscopy can yield a great deal of information about birefringent samples.  Here is the spectrum of a dichroic fiber with both parallel and crossed polars.  A great deal of information can be obtained by adding polarization microspectroscopy to your test protocol.

Polarization Imaging

Imaging of birefringent samples

Polarization imaging can easily and rapidly differentiate between samples, delineate mechanical stress and even for contrast enhancement. Flat panel display

CRAIC Technologies provides service and support for it's instruments worldwide.  CRAIC Technologies service engineers offer instrument repair, maintenance, training and technical support for all aspects of CRAIC Technologies products.

The 20/20 PV™ Microspectrometer can take spectra and images of microscopic samples 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.
