About the High Power Fiber-Coupled LED Light Sources (UV, VIS and NIR)

Mightex FCS-series fiber-coupled 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). FCS series also features a locking electrical connector for secured connection. FCS 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 FCS LED source, one can use any one of the wide range of LED controllers Mightex has to offer:

Features

  • Software controlled LED controllers; or
  • Manual LED drivers.
  • Software controlled LED controllers, Model# SLC-FA04-US; or

Ordering and integration

What you need with it

In the box (Mightex packing list)

  • 1x FCS-series LED light source;
  • 1x ACC-FCS-C05 cable.

Required, ordered separately

Notes from Mightex

  • For deep UV LED sources with an operating current rating of <50mA, it is strongly recommended that the following LED controllers be used to drive the LEDs:
  • (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.
  • Fiber patch cords need to be ordered separately.

Combining this with other equipment? Ask for an integration check.
