19 Aug 2020 In Lumencor’s SPECTRA III light engine, 8 individually addressable solid-state light sources join forces with advanced electronic control systems to achieve unprecedented performance. The constituent light sources include LEDs, luminescent light pipes and lasers. Their outputs are refined by bandpass filters and merged into a common optical train directed to the light output port on the front panel. The light output port has a built-in adapter for connection to microscopes and other bioanalytical instruments through a standard 3 mm diameter liquid light guide (LLG), delivering about 500 mW per channel for excitation of DAPI, CFP, FITC, YFP, TRITC, mCherry, Cy5 and Cy7. The SPECTRA III also features a control system based around an onboard microprocessor and resident GUI providing operating status reports, preference settings and active output stabilization.
