The BUCHI polarization interferometer

BUCHI has 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.  

Easy-clean design increases food safety day by day

The hygienic easy-clean design and high ingress protection (IP) support your routine work in harsh environments. The NIRMaster™ Essential is available in food-grade PMMA housing offering IP54 protection.

FT-NIR Twin Lamp Module

The twin lamp module

BUCHI has set a new standard in terms of the availability of an NIR spectrometer.Our NIR spectrometers are equipped with a twin lamp module, which will automatically switch to a second integrated lamp in the event of a failure of the primary source. This minimizes the risk of an instrument failure, and sufficient time is left to order a replacement lamp. Meanwhile you can continue your measurements without further intervention.
