摘要 |
Disclosed are spectrophotometer, polarimeter, and ellipsometer systems which have multiple easily, sequentially, positionable detector systems therein mounted to allow easy positioning thereof, to for instance, allow sequential monitoring of ellipsometric and spectrophotometric signals, without removal of any detector system from the spectrophotometer, polarimeter, or ellipsometer system. Also disclosed are methods of use wherein-different detectors in a positionable multiple detector containing system are utilized during different electromagnetic beam detection steps.
