A dichroic mirror inside the EDC passes the filtered path 2 light to the вЂњrearвЂќ output of the EDC as well as reflects the filtered path 1 light to the same output. Separate filters on each input of the EDC filter the xenon light to create the individual excitation wavelengths. In addition, the mirror may also be set to a third position that provides high speed shuttering of the excitation light by directing the light away from both input paths. In path 2, a second lens collimates the xenon light before it enters the вЂњfrontвЂќ input of the EDC. In path 1, the now diverging xenon light is collimated by a quartz lens and is then steered into the вЂњsideвЂќ input of the excitation dichroic cube (EDC). A front-surface beam steering mirror positions the focal point of the beam just beyond a galvo-driven mirror that rapidly alternates between two separate paths. The light output of a 75 W xenon-arc bulb is formed into a converging beam using a parabolic reflector within the xenon housing. This figure illustrates the optical path and components of the IonOptix HyperSwitch Dual Excitation Light Source.

The HyperSwitch can also produce hardware video-locked wavelength switching. Wavelength switching is accomplished in less than 1msec and can be continuously alternated at rates as high as 250 pairs/sec. In cases where highest time resolution is essential, the IonOptix HyperSwitch Light Source is recommended.
