Concentrator Flash Solar Simulators

The Sciencetech FLASH-ST pulse stretcher is capable of stretching flash pulses from Sciencetech's standard 120VAC or 220VAC flash power supplies. The FLASH-ST can produce pulses with an intensity stability of +/- 5% over a 3ms temporal width. This pulse stretcher will reduce the peak intensity by 25% as it spreads the energy produced by the lamp over a wider time. Sciencetech also produces flash power supplies that can produce flat top pulses over different pulse widths. Please speak with your authorized Sciencetech technical sales staff to determine how we can make a Pulse Stretcher Unit to meet your specific technical requirements.
Please note that a power supply, flash bulb, and flash head are required for operation and are sold separately. This unit only works with the 2400RS flash power packs (590-0129 for 120VAC, 590-0120 for 220VAC)

The FLASH-ST4 pulse stretcher integrates with Sciencetech flash light sources and solar simulators that operate with the 2400RS power pack.
The stretcher is connected in-line between the power pack and the flash light source or solar simulator housing. The FLASH-ST4 stretches pulses to 4ms +/-3% stabity level.
In most cases using the FLASH-ST4 reduces the maximum intensity level achievable by the light source. Typically maximum peak intensity levels are reduced by 1/2 of simulator or light sources peak specified Sun or intensity level.

Sciencetech can produce customer flash pulse stretchers depending on your design requirements. Please talk to a technical support representative for more information.

Sciencetech’s FSSC flash solar simulator is designed to illuminate small photovoltaic devices up to 5cm × 5cm in size with up to 4000 Suns peak intensity. The default spectral match is to ASTM AM1.5G, using a heavy-duty xenon flash lamp and spectral filtering. The flash is 500µs at 90% of peak intensity, and 2.5ms at 50% of peak intensity, but pulse stretching options are available for longer, flatter pulses (purchased separately). The uniformity of the system is better than 2% at the target plane.

This product includes a flash system, power supply, and lamp. Air mass filters are sold separately (AM1.5G). Other filters are available at additional cost. Available accessories include IV measurement systems, pre-configured host computers, and sample holding and cooling options.

Spectral Match: Class A
Spatial Non-Uniformity: Better than 2% at the target plane
