Custom Illumination System
Photo shows an example of one custom made Scrambler illumination system that provides computer controlled switching of fiberoptics in about 15ms from one position to the other. This allows single source illumination, rapid alternate or simultaneous illumination of the specimen with both trans and epi illumination. Many other illumination permutations are possible utilizing the dual six-position filter wheels.
The system is built around our Triple Lamp Mount (TLM) and has a choice of three source lamps, a Xenon 75W arc lamp on the left, a centrally located HBO 100W mercury lamp, or a 12 W quartz halogen lamp on the right. The system incorporates three computer controlled air actuated Dual Fiber Switches (DFS) only two of which are shown; the third DFS is on an Output Module which can switch its source from Xenon or Mercury arc to provide light to an Olympus epi-illuminator attachment. One Output Module is shown attached to the TLM on the left and provides scrambled Xenon illumination when the source DFS directs it on that path.
Two six position stepper controlled filter wheels are incorporated. One attenuates the light from the Xenon lamp. The other is in the primary illumination path and has a circular grey wedge wheel as well as a six position filter wheel. A 3 slot 2" by 2" filter box is shown between the wheel and the TLM.
This system is at Kyoto University in Japan. The lamphouses are by Olympus Corp, the filter wheels by Technical Video, Ltd. and the illumination dovetail rail on which these devices are mounted is on that microscope. In practice the illumination rail is mounted to the top of the four foot main rail on which are mounted all of the optics. In the picture the two yellow air hoses on the Dual Fiber Switches have been truncated for clarity.
