Microscopy LEDs

Mightex microscope LED 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 using a microscopy light source. 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.

Microscopy LED Application Examples

Abdelfattah et al., developed novel chemigenetic indicators for in vivo voltage imaging in neurons. To illuminate their indicators, the group used Mightex’s Microscope LEDs.

In this work, Crandall et al., used Mightex’s Microscope LEDs to optically stimulating different neuronal pathways connecting to pyramidal neurons found in L6 of the whisker somatosensory cortex of mice.

To study phase resetting curves in vivo, Higgs and Wilson used Mightex’s Microscope LEDs to establish whether their novel method of optogenetic barrage stimulation would work during extracellular spike recordings (a recording method often used in in vivo experiments).
