BioLED Optical Head: Fiber-Coupled and Single Color LED's

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.

Mightex BLS-series fiber-coupled LED light sources employ the latest high-power LED technologies and a proprietary coupling optics to achieve maximum optical output power. In conjunction with BioLED light source control modules, these LED sources are ideal for optogenetics and other bio-photonics applications.

Key features:

• Broad wavelength selections, from 240nm to 940nm
• Interchangeable fiber patchcord, ranging from 50µm to 1000µm core diameter
  
• High output power, e.g. 16mW@470nm (in "IntelliPulsing" mode) with a 400µm 0.22NA fiber
• High stability (spatial and temporal)
• Fast switching time (~µs)

Note: * - measured with a 400µm core 0.22 numerical aperture (NA) fiber. Output optical power scales approximately linearly with fiber core area and NA². With a 400micron-core 0.39NA fiber, the output power will be 3.14x as what has been stated in the table above. For example, for the 470nm wavelength, the output power will become 25mW in CW mode and 50mW in "IntelliPulsing" mode, instead of 8mW and 16mW (respectively) as shown in the table above.
