The applicatioin for the laser diode is for an illuminator for the ophthalmic imaging device . The wavelength and optical power are important. The 808nm diode is used for an ICG fluorescence application. At this point, we are comparing the 780nm and 808nm as well as the 0.2 watt vs the 1.o watt emission.
