The unique design of m·u·t‘s fiber optical beam splitter fits perfectly for all applications that requires a beam separating optical device. It has been developed especially for fluorescence applications. The heart of the fiber optical beam divider is a filter holder for dichroitic filters (1"x1,5") with two rectangular positioned filter holders for standard filters (_ 1"). The filter holder is mounted in a metal housing with three SMA connectors and collimating optics. For easy handling the filter holder can be replaced very easily, without optical adjustments.

Fluorescence measurement

Fluorescence measurement is the most common application for fiber optical beam divider. As shown in the graphics the dichroitic filter separates the UV light from the high-energy light of the light source from the fluorescence emission of much lower intensity. By separating the excitation wavelength from the emission wavelengths the bright light from the light source does not drive the spectrometer into saturation. Additional filters in the light beams from the light source and towards the spectrometers may be used for further wavelengths selection.

Light source monitoring

When inserting a beam splitter, a part of the light from the light source can be separated before entering the measurement setup. The separated beam can be used for monitoring the light source while measuring.

Dual spectrometer mode

Splitting the beam with a dichroitic mirror, two beams with separated spectral range can be examined by two specialized spectrometers to provide a more detailed examination than is possible with one broadband spectrometer.

Pointing the region of interest

Coupling the light of a laser diode into the light beam from an UV or IR light source makes the original light beam visible. That makes adjustments on the optical setup much easier and safer.
