Supercontinuum light source Cavity-Ringdown Reflectometer


GLACIER®-C is a further development of our successful GLACIER® reflectometer. GLACIER® allows measuring the losses of optical coatings down to 5 ppm using the extremly sensitive cavity ring-down spectroscopy method. It is therefore often used to characterize highly reflective mirrors where conventional reflection and absorption measurements are insufficient. The innovation of GLACIER®-C is the employment of a super- continuum laser source in combination with a tunable monochromator. This allows a freely selectable wavelength within 450 nm and 2000 nm and, thus, offers an unprecedented flexibility as it is not limited to available diode laser wavelengths. GLACIER®-C combines the unrivalled sensitivity of GLACIER® with a unique wavelength flexibility, creating the most powerful device on the market. The device features high-speed data acquisition and allows to record measurements within seconds. Easy and fast change of wavelength is facilitated through the user friendly software and easy change of optics on kinematic mounts.
