Introducing iStar for Spectroscopy
Andor’s iStar extracts the very best from CCD sensor and image intensifier technologies, achieving a superior combination of rapid acquisitions rates and fast, accurate gating performance. Exceptional detection performances are accessed through high quantum-efficiency image intensifiers, thermo-electric cooling to -40ºC, 500 kHz photocathode gating rates and enhanced intensifier EBI noise reduction. Low jitter, low insertion delay gating electronics and nanosecond-scale optical gating provide excellent timing accuracy down to a few 10’s of picoseconds, allowing ultraprecise synchronization of complex experiments through iStar’s comprehensive range of input/output triggering options
