The L11416 series is a test tube type easily mounted in lab devices such as for blood sampling, while the L11494 series is a plate type designed to be placed on a sample stage. Stable continuous light of approximately 1 pW is always output because the LED emission power is controlled by monitoring with a photodiode.
