New PlexBright™ Dual LED Commutator

Plexon is pleased to announce the launch of our new PlexBright™ Dual LED Commutator along with the seven new compact LED Modules and commutator specific patch cables, expanding the PlexBright LED Optogenetic Stimulation System  product line. The PlexBright Dual LED Commutator is a light-weight, low-torque design that supports optogenetic experiments with animals as small as mice.

A range of specialized Compact LED Modules have been engineered for use with the commutator that mirror wavelengths available in Plexon’s Table Top LED Modules – royal (450nm), blue (465nm), green (525nm), yellow (590nm), orange (615nm), red (625nm) and crimson (645nm). This commutator supports the use of either one or two compact, super intensity LED modules. When operating two compact modules simultaneously, each one may either be driven independently or they may share the same signal, such as for bilateral stimulation.

To complete the package, unique PlexBright Optical Patch Cables  have been designed to maximize performance when utilizing this new commutator. Hands-on training will be provided for the PlexBright Dual LED Commutator, PlexBright Compact LED Modules and the Plexbright Optical Patch Cables for commutator use during the upcoming Annual Neurophysiology Workshop.
