The Prizmatix Optogenetics-LED-STSI is a powerful fiber coupled pulsed LED light source designed to provide high power light for Optogenetics Stimulation / Silencing to the same neural structure in freely moving animals.

This Optogenetics LED contains two independent internal LED Lights of different colors which are combined into a single SMA output. Each light is capable of providing powerful light pulses of up to >220mW/mm2, triggered by external TTL input.

The Optogenetics-LED-STSI system enables bilateral activation / inhibition with single device and single one-channel rotary joint for significant cost saving and without compromising power at implant tip.

The STSI-Optogenetics-LED is available in any combination of the following wavelengths*:

• Ultraviolet: (~385nm)
• Violet: (~400nm) over 380mW/mm^2
• Blue: (~455nm) over 440mW/mm^2
• Green: (~520nm) over 120mW/mm^2
• Lime-Green: (~545nm) over 440mW/mm^2
• Yellow: (~595nm) over 80mW/mm^2
• Orange-Red: (~625nm) over 250mW/mm^2
• Deep Red: (~655nm) over 120mW/mm^2

*Other wavelengths from 365nm to Near Infrared, are available by request.
