FLEX™ UV-Visible-NIR Microspectrophotometer - CRAIC Technologies



FLEX™ from CRAIC is a full-featured yet flexibly configured instrument that incorporates UV-visible-NIR optics, spectrophotometers digital imaging, and software…all tied together with our Lightswitch by CRAIC™ optical multiplexer. With our Lightswitch by CRAIC™ technology, FLEX™ retains the ease-of-use for which CRAIC instruments are known, while being capable of everything from UV-visible-NIR microspectroscopy, high resolution microscopic imaging, refractive index measurements and more.

With an attractive price-entry point, the FLEX™ microspectrophotometer utilizes tested technologies to allow you to measure UV-visible-NIR range transmission, absorbance, reflectance, emission and fluorescence spectra of microscopic sample areas. And while microspectra™ are being acquired, the sample may be simultaneously imaged with a high-resolution color digital imaging system or through eyepieces. Additional features may also include measuring the refractive index of microscopic samples as well as microcolorimetry and microspot thin film thickness measurements.

The FLEX™ microspectrophotometer is built to yield superior quality images and spectra for an attractive price.

UV-vis-NIR Microspectroscopy

Cost effective microspectroscopy

Microspectroscopy that features a spectral range from the UV through the visible and into the near infrared. Simultaneous and direct imaging of both the sampling aperture and the sample makes for fast, accurate measurements. Featuring Lightblades™ technology, the FLEX™ gives you the ability to measure transmission, reflectance and fluorescence spectra of even sub-micron samples.

Holmium Oxide Absorbance Spectrum

CRAIC Technologies is also the only recognized source for NIST traceable microspectrometer standards.

Raman Microspectroscopy

Flexible Raman Microspectroscopy

When fitted with the CRAIC Apollo™ Raman spectrometer module, the FLEX™ is capable of Raman, resonance Raman and other types of measurements of microscopic samples. Modules include lasers, Raman spectrometers and the interface optics that allow you to collect high quality Raman spectra of your samples.
