The SR-1901PT measures the spectral distribution of both continuous and pulsed solar simulators
Most commercial solar simulators use bulbs that may shift in wavelength over time; therefore it is important to measure the spectral output of a simulator to certify that it still falls within its rated class of performance. If the system drifts off class A output, it may be necessary to add additional filtering to the system and make additional adjustments to the power level of the bulbs to maintain the desired class of performance.
SPECTRAL EVOLUTION’s SR-1901PT spectroradiometer is designed to measure the spectral distribution of both continuous and pulsed solar simulators for AM0, AM1.5 and AM1.5 Global tilt. The SR-1901PT has a broad spectral range of 280-1900nm, ensuring that each interval is adequately covered.
SPECTRAL EVOLUTION’s SR-1901PT spectroradiometer allows end users to validate Class A performance of solar simulators very quickly and easily with minimal set up time. The small size and weight of these systems (~11x8x3 inches; 7lbs) means that they can be set up anywhere as space dictates.
The SPECTRAL EVOLUTION SR-1901PT spectroradiometer has a compact footprint for use with any solar simulator. It communicates via wireless Bluetooth with any Windows 10-based laptop or desktop computer for easy setup. The irradiance diffuser (inset) is easy to place within the illumination zone and can be moved throughout the measurement plane for verification of uniformity. The irradiance diffuser also features a photocell sensor to detect the initiation of a pulsed measurement. A 2 meter fiber optic assembly is offered; longer lengths are available.
