Fiber-Coupled LEDs

Mightex BLS-series BioLED light sources are modularized fully-customizable turn-key solutions for optogenetics, fluorescence excitation, and other biophotonics applications. Precisely-timed and high-intensity light pulses are required in optogenetics experiments to activate channelrhodopsins (ChR2, ChR1 etc.) and halorhodopsins (NpHR) in order to excite and inhibit neurons. To meet these requirements, Mightex has developed a proprietary “IntelliPulsing” technology to allow BLS-series sources to output significantly higher power in pulse mode than what the LEDs are rated for in CW mode.

Optogenetics Starter Kit

Mightex’s optogenetics starter kits are ready-to-use turn-key solution for ChR2 stimulation, and they feature super-high output power (up to 7.2mW with a 200µm fiber) and ultra-low power variation (<2%) during rotation. The optogenetics starter kit is typically composed of the following items:
