Table-Top LED Modules for Optogenetics

At the heart of the PlexBright^® Optogenetics Stimulation System are the cost-effective and powerful Optogenetic LED Modules for standard use, Table-Top Modules. A full spectrum of wavelengths enables you to get the most out of your research whether you are performing acute or chronic in vivo experiments or in vitro preparations.

**NEW Near-infrared and Ultraviolet LED Modules.**

Description

PlexBright Table-Top LED Modules for standard use are small devices most often chosen to support: 1) in vitro work; 2) in vivo experiments with anesthetized animals, or; 3) in vivo experiments with behaving animals when a commutator is not required to prevent tangling of cables.

Optogenetic LED Modules come in a wide range of wavelengths and are capable of emitting continuous, stable, and quick-responding light through the tip of a 200μm core, custom developed optical fiber. Table-Top LEDs are available in the following seventeen wavelengths: Royal (450nm), Blue (465nm), Green (525nm), Lime (550nm), Yellow (590nm), Orange (620nm), Red (630nm) Crimson (660nm), Infrared 1 (850nm), Infrared 2 (940nm), Near-Infrared 1 (740nm), Near-Infrared 2 (760nm), Near-Infrared 3 (780nm), Near-Infrared 4 (810nm), Ultraviolet 1 (365nm), Ultraviolet 2 (385nm), and Ultraviolet 3 (405nm). Our ever-expanding series of powerful, fiber-coupled PlexBright LED Modules effectively elicit responses from several opsins targeted in neuroresearch, including channelrhodopsins (ChRs), archaerhodopsins (Arch) and halorhodopsins (NpHR).

For maximum power output to the stimulation site, high performance PlexBright Optical Patch Cables have been designed to easily connect to the modules. It is important to note that our PlexBright Optical Patch Cables are LED module style-specific.

Optogenetics Starter Kits offer the initial products to get started. Kits are available in four experimental designs and with either driver (the economical kit with the LD-1 Single Channel Optogenetics LED Driver or the fully functional kit with the PlexBright 4 Channel Optogenetic Controller with Radiant Software).

In addition to super intensity PlexBright LED Modules, Optical Patch Cables and Commutators, the PlexBright Optogenetics Stimulation System also offers the PlexBright LD-1 Single Channel LED Driver; the more sophisticated PlexBright 4 Channel Optogenetic Controller running Radiant^™ Software; specially designed PlexBright Fiber Stub Implants; the PlexBright Light Measurement Kit; and the PlexBright Optical Fiber Cleaning Kit to safely maintain and extend the life of the fiber tips. If your experiments include freely behaving animals, you may also be interested in learning more about the CinePlex^®and CineLyzer^®Behavioral Research Systems.

Your Plexon Sales Engineer is available to provide additional information and to assist you in determining what configuration might be the best choice for supporting your research.

PlexBright LED Power Output at Various Points Throughout the Light Path

With High Performance Patch Cables

Table-top and Compact LED modules offer identical power output specifications for a single wavelength/color.

Most information provided by other companies will report the highest possible output power – often directly from the LED itself. Plexon is more concerned with ensuring that researchers are clearly aware of practical output. The table below provides the expected system output actually experienced by the tissue – accounting for the specific wavelength chosen, loss due to patch cable and fiber stub connections, and the Fiber Stub Implant optical fiber diameter.

*** Important Power Output Note ** Plexon is committed to ensuring that researchers have the most accurate data available regarding the equipment used for their research. Therefore, we have taken extra care to provide the typical power outputs that are actually experienced at the tip of a 1.0m PlexBright Optical Patch Cable attached to a PlexBright LED Module. Other companies typically present the power output from the module itself, which represents the highest value possible. However, a more realistic number is that of the power output from the tip of an attached optical patch cable of appropriate fiber size, The information below represents the more realistic performance – and is only achievable if using the PlexBright high performance products. Any substitutions will not yield the high powers reported below. If comparing PlexBright products to those of other companies, be certain to verify if the power output reported is directly from the LED module, or the LED module plus 1.0m optical patch cable.
