1. Mircofluicdcs
2. Design for Light in spatio-temporal
Multiple devices of optics are designed and created for the various requirement of experiments. All devices are attempt to modulate the spatio-temporal pattern elegantly and effectively.
2.1 Device One: Arduino modulate Mercury lamp
A simple and effective device to output pulse of certain wavelength of light. On time and off time of pulse is custom by Arduio. Wavelength of light is modified by replacing filter before beam expander.
2.2 Device Two: Projector Tracker
= 2.2.1 Basic mechanics and optics=
We need 395nm light to activate Calcium indicator protein GEM-GECO by Lumencor LED Illumination. Then both red light and blue light activate CoChR or Chrimson by LCD projector. LCD projector and LED Illumination are merged by a double LH Adapter contained a semi-transparent mirror. Double LH Adapter connect to entrance of light in microscope. So we can use these two light source together.
We choose projector as red and blue light source, because we can activate single cell or C. elegans with adjustable color and strength.
Because the focus distance of origin lens in projector too short for microscopy, a longer focus distance lens is replaced. We install a new lens in projector.
To purify light form projector, origin blue channel filter is replaced in Chroma ET480/20X and red channel filter is replaced in Chroma ET630/20X. Dimirror is 89402bs, and emssion filter is 89402m.
