Where to Buy White Light Interferometers

Thorlabs manufactures a robust benchtop white light interferometer for characterizing reflective and transmissive dispersive properties of optics and coatings designed for ultrafast applications. The Chromatis™ dispersion measurement system covers 500 – 1650 nm, providing a means for measuring optics used for common femtosecond systems, including Ti:sapphire systems as well as 1 µm and 1550 nm oscillators. The Chromatis compliments our ultrafast family of lasers, amplifiers, and specialized optics including nonlinear crystals, chirped mirrors, low GDD mirrors/beamsplitters, and dispersion compensating fiber.

GOBI, the white light interferometer from UltraFast Innovations (UFI®), implements spectrally resolved interferometry to accurately measure the group delay dispersion (GDD) of multi-layered ultrafast optics. The device has been developed to characterize and refine some of the most advanced coatings to date. GOBI offers unique spectral coverage of up to 250–1100 nm (UV/VIS/NIR version) and 900–2400 nm (IR version). Spectrally resolved detection makes reference lasers obsolete and removes restrictions concerning any related test samples. This opens the full spectral range for characterizing even ultra-broadband or advanced narrowband coatings. The flexible optical setup can be used for mirrors and transparent samples under angles of incidence between 0° and 70°.
