Thank you for the interest in my poster at CYTO 2017 in Boston about testing dichroics, the 20 handout copies that I had available were all gone so I’ll take that as a good sign.  I’m working on a writeup with more examples and another test to run, but in the meantime have linked my poster here if you wanted to check it out, along with the email contacts for the vendors of the GoSpectro smartphone spectral analyzer:

Let me know if you have any questions, and I’m hoping to add more content in the near future…
