and co-founder. Samurai. And it's a rock we manufacture high performance optical filters that are used in a variety of different applications. And today you wanna talk to -- about very very special product that we just came out with this year. Where do you balance that asking a question. Did you know that you can then an optical filter and film optical filter over sixty. Or even eighty nanometers across the visible lately range. And did you know that you can do this while maintaining all the great properties of thin film filters like. -- transmission. Very steep spectral edges wide out of -- blocking and perhaps most importantly. The ability to transmit an image through the filter volume -- may not believe what I just told you so let me actually show you we have a demonstration here and all this is as a white light light emitting diet. That's pollinated and being transmitted through one of our new -- optical thin film filters . And that filters being rotated from zero to sixty degrees and back again. Here haven't been -- that's picking off a little bit of the lights like image of the spectrum and show it to you real time and then the -- transmitted onto the screen back here. Now up here we're actually showing the spectrum that's being measured of this band pass filter. And this the filters actually designed to transmit light between -- about 620 nanometers. When it's abnormal incidents all the way down to about 550 -- when it's at sixty degrees. -- seventy nanometer tuning range for this particular filter all while transmitting. A potentially two dimensional imaging beam of light through the filter. So why it's suitable filters matter why should anybody care about having it good -- built especially one that transmitted images. We'll take -- all biological imaging

cause of death -- crime -- Now you might be -- yourself filters have been around for a long time so what's new about this technology. Well -- think they'll filters are regarded by many people as really the ideal spectral filtering technique. For especially optical imaging systems because of their high transmission very steep -- edges and wide had -- blocking however. Filters have long been regarded as a truly fixed filtering and it. That is if you -- change the spectral characteristics you have to have multiple filters and you have to swap them somehow using for example filter -- Now on the other hand. A fraction ratings are --

great. Some rocks new -- chrome and wolf that -- them optical filters . Technology is something truly unique and we're very excited about implementing -- wide range -- applications. If you have any questions at
