Vincent / UniBlitz SD-1000 Shutter Drive / Timer

The Vincent / UniBlitz SD-1000 Shutter Drive / Timer delivers precision exposure control for UniBlitz electro-programmable shutters in demanding scientific and industrial imaging environments. Crystal-controlled timing accuracy of ±0.01% combined with variable recycle intervals and selectable repeat exposure modes enable repeatable, frame-accurate shutter sequencing from microsecond to multi-second exposures.
