The two modes provide two measurement accuracy ranges: standard delay range and low delay range. Standard retardation provides ± 10 nm retardation measurement accuracy from 0 to 316 nm and ± 3 ° azimuth measurement accuracy over the entire measurement range. The low retardation provides ± 1 nm retardation measurement accuracy from 0 to 100 nm and ± 1 ° azimuth measurement accuracy over the entire measurement range. The shortest exposure time is 0.021 ms and the longest exposure time is 7330 ms.
