GLACIER®-C — Supercontinuum Cavity-Ringdown Reflectometer (Broadband Loss Metrology)
Design Tools
GLACIER®-C is a broadband version of the GLACIER® reflectometer, replacing single-wavelength CW lasers with a supercontinuum light source. This enables continuous-spectrum reflectivity / transmission measurements across a wide wavelength range — ideal for characterizing chirped-mirror coatings, dispersion-compensated mirrors, and ultra-broadband optics that require spectrum-resolved metrology.
GLACIER-C inherits the single-ppm precision of the GLACIER platform but provides full-spectrum data in a single measurement, eliminating the need for multiple discrete-wavelength runs.
Key Product Features
- Single-ppm sensitivity across full broadband spectrum
- Supercontinuum source — continuous wavelength coverage
- Ideal for chirped-mirror & dispersion-engineered coatings
- Single-measurement broadband loss curve
- Compatible with high-reflectivity coatings (R > 99.999%)
- Automated software with intuitive interface
