The Plexon OptoPlex LED-based optical stimulation system is an afforable, turn-key solution for optogenetic experiments. Using new LED-fiber coupling technology, the OptoPlex system can deliver power output comparable to that of high-priced lasers. With the LED light source, the OptoPlex system provides more constant light output over time compared to many laser systems, which suffer from transient fluctuations at onset and varying light output over time due to temperature changes.
The Plexon OptoPlex light stimulation system is a flexible optogenetic stimulation solution, and is available in multiple wavelength options - 460/470, 525, 590, and 615/625 nm. The LED module can be configured with either 125/140 µm or 200/230 µm (ID/OD) fibers for use in both chronic and acute preparations. All necessary accompanying interconnects and implantable ferrules are availabel through Plexon.
