Mightex Multi-Wavelength Beam Combiners for LED Collimator Sources Description：

Datasheet

Mightex Multi-Wavelength beam combiners combine two LED collimators of different wavelengths into a single collimated beam. Multiple combiners can be cascaded to combine more than two LED collimator sources. At the heart of the beam combiner is a high-performance dichroic beam splitter that combines two wavelengths with >95% efficiency. A neutral beam splitter is also available as a lower-cost solution for applications where maximum light throughput is not required.

Beam combiners are characterized by the edge wavelengths of their dichroic beam splitters. Please use the following diagram and check the Specification table to select the correct beam combiner for intended LED collimator source.

The beam combiner includes multiple mounting holes and threads so that it can be easily integrated into a system. Each input port features a fine 2-axis tilt adjustment to allow precise alignment of the LED collimator sources relative to system optical axis. A robust locking mechanism is also provided to maintain alignment over time. Additionally, adapters are also available for coupling to major brands of microscopes.

Adding optical filters to the input ports

A filter well (see diagram below) is integrated into each input port so that a φ1” or φ25mm optical filter can be inserted in between the LED source and the beam splitter. Narrow band filters and polarizers may be used to clean up LED spectrum or change the polarization state of the output beam. Here are the dimension requirement for the dichroic/beamsplitters to be fit into the beam combiner cubes:

Length: 34~36mm

Width: 25~26.5mm

Thickness: 1mm recommended, 1.5mm max.

Connecting multiple beam combiners

Multiple beam combiners can be connected using connecting plates (sold separately).

Connecting 11-mm aperture collimated LED sources

Currently, Mightex’s multi-wavelength beam combiners can only be used to DIRECTLY combine 22mm-diameter Collimated LED Sources. For 11mm-diameter collimated LED sources, (as shown below) a mechanical adapter (P/N: ACC-BC25-011) can be used to attach the LED sources to the beam combiners, before the 11-mm diameter collimated LED sources can be combined. We don’t yet have beam combiners for 38mm- and 48mm-diameter collimated LED sources.
