*1: Internal: Adjustable with a trimmer
*2: External: Variable with control voltage from 3.2 V to 4.8 V
*3: External: Variable with control voltage from 2.44 V to 4.88 V
*4: Light output stability (at a repetition rate of 10 Hz or more)
Light output stability (% CV) = light output standard deviation / average light output × 100
Light output stability (% p-p) = (maximum light output – minimum light output) / average light output × 100
*5: Measured with a Hamamatsu Si photodiode S1336-8BQ. The life is defined as the time at which the light output at 190 nm to 1100 nm decreases to 50 % of the initial output level or the light output fluctuation exceeds the specified maximum value when the lamp is operated at 5 W.
*6: External trigger only, synchronized at rising edge
*7: Cooling is necessary if the housing temperature exceeds 45 °C during operation.
