Fiber coupler for the EQ-99X – high luminance and very wide spectral range

Efficient light coupling into multi mode fibers

Lots of light from multi mode fibers with small diameter

Energetiq’s laser-pumped EQ-99X LDLS ™ is a high-luminance, free-beam light source with a very broad spectral range from 200 nm to 2200 nm.
With our fiber coupler it is possible to couple its light efficiently into a multimode fiber. The plasma of the EQ-99X is imaged onto the fiber end with an off-axis ellipsoidal mirror. This works optimally for fibers with a diameter of 200 – 400 μm.
The adjustment is done via only three screws and is quick and easy to accomplish.

With an integrated filter slider, a 1′ filter can be brought into the beam path. A Zero Aperture Iris Diaphragm is used to adjust the output power between 0 and 100%.
