The Verifire QPZ represents Zygo's newest Fizeau interferometer designed for uncompromised production metrology. A true laser Fizeau design, the Verifire QPZ utilizes proprietary methods to ensure reliable "ripple-free" phase measurements in vibration prone environments. Compatible with all standard Zygo accessories the Verifire QPZ is the one interferometric solution that can be trusted to provide accurate surface metrology in both production and QC environments – without compromise.
PSI enables metrology in environments with vibrations of a magnitude of up to ~150 nm. A passive isolation system is recommended with PSI acquisition.
