These lamp modules integrate a 2 W xenon flash lamp with a power supply and trigger socket, and are designed to extract maximum performance from the lamp. The lamp is available in a housing that has the smallest size among lamps of comparable wattage and operates on a 5 V battery to allow assembly into portable analytical instruments.

*1: Internal: Adjustable with a trimmer
*2: External: Variable with control voltage from 3.2 V to 4.8 V
*3: 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
*4: 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 2 W.
*5: Time until the lamp operation stops under the following conditions (spectral irradiance and light output stability are not considered).
Input voltage: 5 V, main discharge voltage: 600 V, main discharge capacitance: 0.141 μF, repetition rate: 79 Hz, battery specs: 5400 mAh / 3.7 V
*6: External trigger only, synchronized at rising edge
*7: Cooling is necessary if the housing temperature exceeds 45 °C during operation.
