| Research Abstract |
In this study we developed a microscope equipment with which photosensitive molecules can be stimulated. In the equipment a pair of potassium tantalate niobate (KTN) crystals were used as a tunable lens, an electro-optic device that changes its refractive index by voltage. By changing the voltage which applied to the tunable KTN lens focus changed within ~23 microseconds. The speed of focus change was about 500~1000 times faster than that of the conventional piezo focuser. This technique can be applicable not only to scientific researches including neuroscience but also industrial field such as laser processing.
