Transmission of white light through dichroic filters, in a) measured transmission of HCA white light source, in b) transmission spectrum specified by the vendors. Spectra shown in a) were measured on different dates with slightly different system alignments; however the relative efficiency is indicative of the performance differences expected according to the transmission efficiencies shown in b). In a) the reference white is lower in intensity than the intensity transmitted through the Semrock dichroic, this is an artifact of both the normalization and slight changes in the optical path between the dates when these spectra were acquired.
