Request InfoAvantes BVAvantes BV has announced a new optical bench design integrated into its AvaSpec ULS2048 fiber optic spectrometer. The AvaBench75-ULS2048 has a dual internal mode stripper and multiple compound parabolic concentrators to reduce stray light levels down to 0.04%. The new design features high rigidity, decreasing by a factor of 20 strain sensitivity caused by microbending. Applications include high absorbance unit measurements, long optical path measurements and high optical density measurements.
