June 20, 2013 Time Contribution Tibi R&d optics work 2.05 HR 31 MAY 2013 I produced a few filaments and put a mirror on their tip. I used 125/63.5 MM glass Infinicor300 Corning fiber, pulled with the microsplicer, voltage used 8.5V, max current. I pulled the fiber by hand using the manual micrometers on the device. One can diminish the voltage down to 8V. 7V is not enough to melt the glass fiber. At 8 one can do finer stretches. The tip of the pulled micro fiber was melted to round it, and was coated using our inhouse wet silver coating method. Only the very tip was coated. I tested them with red light to see how and where they leak. One problem is to make them straight, without undulations. The goal is to test them with the 850nm LED Mosquito and with the 1550nm Chinese Mosquito. I worked 4 hours. 2 JUNE 2013 I coated another one and prepared the Mosquitos for experiments. I will continue the work tomorrow. This work needs some documentation, I will also do that next week, as the work will advance. I worked 2 hours. 3 JUNE 2013 I made 2 microfilaments, 1 to 2 mm long, 40 and 20 microns diameter. I tested them with the 850nm LED Mosquito. They didn't seem to work... TODO: I need to test them again with the enhanced Mosquito (wit filter and amp), which was tested in the Joint-type transducer. 14 JUNE 2013 I made 5 microfilaments fibers. The fibers were pulled with the microsplicer. They were coated using our in-house silver coating method, only the tip. I used 2 mixture optical epoxy to seal the tip, to fix the silver coating. I used the Infinicore300 125/62.5 MM glass fiber from Corning. 17 JUNE 2013 I am trying to test the microfiber transducers made the other day using the Chinese Mosquito https://docs.google.com/document/d/1lUcR376j7tqXnkwuLuBDfzvTcqASJ_Lok6zIO2ZZFd0/edit#heading=h.s6bg8bozsa9y I worked with Antonio, we could measure 100 microns displacement, which is OK with the Chinese Mosquito, After this work, Ivan and I went to Phil's to test the microfiber transducers. See report here. https://docs.google.com/document/d/1m-TziGziDZS4v4OJsYezbZBVRrv6p8u4Tyw6N7q-OHs/edit I also spent 1 hour documenting. JUNE 20, 2013 Produced 2 smaller mifrofibers, approx 10 microns each, and coated one of them. Next time I will coat the second one and will bring them to Phil's to test them. We don't have anymore epoxy to seal the tip and fix the coating. We are waiting for our UV LED to cure the optical glue we have.
