Lumencor’s red/green/blue (RGB) light engine has superior power over any lamp based illuminator used in surgical procedures. Moreover, the light engine incorporates powerful NIR sources to strategically excite fluors designed for specific and selective identification of a particular pathology during surgical procedures. The NIR outputs as well as other wavelengths can be used for targeted fluorophore excitation. The light engine may be tuned to match any color temperature. A fourth output may be included, cyan. This is particularly important for minimally invasive surgery where the RGCB components can be balanced to offset red in the surgical field. The LE can provide high blue and green content, to match the camera chip and yield a field of view that images in high contrast. One can then superimpose the fluorophore excitation, giving the surgeon a superior image quality within which to operate.
