NIRFlex N-500

We have set a new standard in terms of continuous operation of an NIR spectrometer.Our NIR spectrometers are equipped with a twin lamp module that automatically switches to a second integrated lamp in the event of a failure of the primary source. This minimizes the risk of instrument failure and you have sufficient time to order a replacement lamp. Meanwhile you can continue your measurements without further intervention.

We have adapted the successful quartz polarization interferometer by using crystals with a very high refractive index. This leads to optimum resolution and a compact design maintaining the advantage of insensitivity to mechanical disturbances. The reason for the superior performance of this interferometer in rough environments is the difference of spatial movements and the optical path shifts for the two light beams in a birefringent crystal of variable thickness. Whereas in a Michelson type interferometer mechanical distortions directly affect the interference, such effects are reduced by a factor of 10 to 20 in a crystal interferometer.

Each BUCHI FT-NIR spectrometer is equipped with various gray filters and a wavelength standard. With these features and specifically designed software modules, you can readily check wavelength accuracy, signal-to-noise ratio, and linearity. These measurements form the System Suitability Test (SST), which is indispensable for meeting regulations in the pharmaceutical industry.
