Hi all, I am searching for a photoresist that is sensitive to visible wavelength of light. especially in 600-800 nm region. I found a conference paper in which SU-8 3050BW. a photoresist sensitive to visible range of light, was used. However, I could not find any information about SU-8 3050BW. Or is it possible to modify conventional photoresist to be sensitive to visible spectrum by using photoinitiator and photosensitizer?
