Mightex Filtered High Power Fiber-Coupled LED Light Sources

(UV, VIS and NIR)
Description

Filtered fiber-coupled LED light sources. Standard SMA fiber adapter port (SMA fiber patch cords are sold separately). Deep UV (255 nm) to NIR (980 nm). Locking electrical connector for secured connection. Users may insert an optical filter into the light source to tailor output spectrum and intensity. (Optical filter not included. Fits standard 1″/25 mm diameter filters up to 5 mm thick.)

Mightex FFC-series filtered LED light sources employ the latest high-power LED technologies and a proprietary coupling optics to achieve maximum optical output power. Optical output is coupled into a fiber through a standard SMA fiber adaptor port (SMA fiber patch cords are sold separately). Users may insert an optical filter into the light source to tailor output spectrum and intensity. Example applications include fluorescence excitation with a bandpass filter, wavelength selection from a white LED, attenuating intensity with a neutral density filter, and polarized output with a polarizer.

Filters are not included in standard FFC products. Maximum filter diameter is 1”(25.4mm) and minimum diameter is 12mm. Maximum filter thickness is 5mm. Filters with diameters of 1” or 25mm can be directly loaded into the filter holder. Smaller filters may need an adapter.

FFC series also features a locking electrical connector for secured connection. FFC series are designed as a universal light source for general lab use and OEM applications. The one-piece machined housing features multiple mounting holes. All Mightex LED drivers such as the SLC series or other LED drivers and current sources can be used to drive the light sources.

To drive a FFC series LED source, one can use any one of the wide range of LED controllers Mightex has to offer:

  • Software controlled LED controllers; or
  • Manual LED drivers.

IMPORTANT: For deep UV LED sources with an operating current rating of < 50 mA, it is strongly recommended that the following LED controllers be used to drive the LEDs:

  • Software controlled LED controllers, Model# SLC-FA04-US; or
  • Manual LED driver, Model# SLA-0100-2.

IMPORTANT : (1) LED’s can ONLY be driven by a constant-current source, and NOT a voltage source (e.g. a battery, or a AC/DC power supply etc.); (2) Please always verify LED’s current rating first before applying current to the LED, and please always make sure NOT to apply current that is above the LED’s current rating.

LED Application Examples

Abdelfattah AS et al., Bright and Photostable Chemigenetic Indicators for Extended In Vivo Voltage Imaging – Science (2019)
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.

Crandall SR, et al.,  Infrabarrels Are Layer 6 Circuit Modules in the Barrel Cortex that Link Long-Range Inputs and Outputs – Cell Reports (2017)
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.

Higgs MH, Measurement of Phase Resetting Curves Using Optogenetic Barrage Stimuli – Journal of Neuroscience Methods (2017)
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).
