LED Parameters at Different Operation Modes
        QUASI-CONTINUOUS WAVE (QUASI-CW) MODE:

Standard regime of operation that we recommend for receiving maximum average optical power is quasi steady-state regime (quasi-CW) with repetition rate 500 Hz. Using of thermoelectric cooler allows optical power to be stabilized or increased (by cooling).
Current Dependences of Optical Characteristics
Optical power is measured in quasi-CW regime (at square-wave modulated bias).

Full power can be measured correctly only by using of integrated sphere.
Power of our LED practically doesn`t decrease with increasing of modulation frequency up to 10 MHz. Spectral intensity is shown in arbitrary untis.
