Nanoquest FT-IR MEMS spcetrometer by Ocean Insight 1350-2500nm


Micro FTIR spectrometer 1350-2500nm


Nanoquest NANOQ-2.5 by Ocean Insight (aka Ocean Optics) is a MEMS based Michelson Interferometer on a chip coupled to a fiber optic input. NANOQ-2.5 offers 1350-2500nm range in a small inexpensive package.

NanoQuest is based on Fourier Transform Infrared (FT-IR) Technology. The sensor’s patented micro-electro-mechanical systems (MEMS) technology allows for a continuous-wave Michelson interferometer to be created monolithically on a silicon chip.  The width of a resonance cavity is varied through time with a moving mirror, and the amplitude of each wavelength showing constructive interference is calculated through Fourier transform function of the time dependent signal.  This enables detection of all wavelengths with a single detector lowering the cost. The small size of the MEMS chip mitigates the effects of motion on sensor stability.

Each NanoQuest comes with an optical fiber and operating software, and can be coupled to Ocean Insight light sources and accessories to configure systems for absorbance/transmission or reflectance measurements.

  • Covers wider spectral range (1350-2500 nm), at lower cost, than other shortwave IR instrumentation
  • Ultra-compact size (smaller than a deck of playing cards) frees up bench space and makes scalability simpler
  • User-selectable optical resolution (8 nm or 16 nm FWHM) and scan rate provide experiment flexibility
  • Versatile setup options enable absorbance/transmission or reflectance measurements
  • Wider range and lower cost make access to shortwave IR measurements more manageable for a greater number of researchers
  • NANOQ-FIBER-400-VIS-NIR is included when you order the NanoQuest
