Transmission spectra from 191-800 nm for various glass and polymer incubation containers acquired using a Thermo Evolution 300 benchtop spectrophotometer. Spectra are reported for passage of light through single thicknesses of fused quartz glass, borosilicate glass, polyvinylfluoride film (PVF, sold under the brand name Tedlar), 4 mil thickness polyethylene terephthalate film (PET, sold under the brand name Mylar), and for passage through both PVF and PET films together. Transmission spectra are reported as percentages.
