White light interferometer GOBI®

GOBI® is the ideal instrument to characterize and control the quality of multi-layered ultrafast optics. The device uses spectrally resolved interferometry to accurately measure the optics in terms of the spectral phase and the Group Delay Dispersion (GDD).

Combining spectral with temporal information and the possibility to accumulate multiple passes over the same optic, the device ensures reliable results. Moreover, in contrast to other devices on the market, GOBI is able to resolve strong GDD oscillations, which is extremely relevant to characterize ultra-broadband or advanced narrowband coatings.

Available for different spectral ranges (Vis/NIR, UV and IR), all options can be combined providing a unique spectral coverage from 250 to 2400 nm.

Add GOBI to your lab to characterize and refine the most advanced coatings to date.
