Sciencetech Solar Simulators

Solar simulators are light sources with specialized characteristics that make them similar to natural sunlight in quantifiable ways. At minimum, solar simulators resemble natural sunlight in their specific spectral match, their low spatial non-uniformity, and their low temporal instability.

Solar simulators are described in terms of their classification in the format: “Class XYZ” in which the position of the letters is fixed:

  Class XYZ: X represents spectral match: the output irradiance is measured in several wavelength intervals. The percentage output irradiance in each interval is measured, and any one interval with the lowest classification match determines the total ranking (e.g. if all intervals but one are Class A, and one is Class B, the spectral match is Class B).

  Class XYZ: Y represents spatial non-uniformity: the output irradiance is measured at a set of evenly spaced points throughout the target area. The upper and lower range of those points determines the spatial non-uniformity classification. It is important to note that this parameter uses broadband measurements and does not break down the light into wavelength intervals.  

  Class XYZ: Z represents temporal instability: the output irradiance is measured over a specified time interval and the upper and lower range of these measurements determines the temporal instability. It is important to note that the relevant time scale for these parameters was determined with regard to silicon photovoltaics, so other applications may have different (including less stringent) requirements.

  Classifications of A+, A, B, and C for each parameter are defined by internationally recognized standards. Class A+ is primarily intended for use in calibration laboratories and is not considered necessary for manufacturing and qualification testing. 

  Other features that are not included in the standard classification but which may nonetheless be important in specific applications include:

  Collimation: the degree to which the rays of light are parallel. Due to the extreme distance between the sun and the earth’s surface, natural sunlight is highly collimated. In many applications, this is not highly relevant, but in others, especially space applications, it may be important. 

  Air Mass Filter: Depending on the specific conditions the solar simulator is intended to simulate, different spectral conditions will need to be adhered to. For example, greater UV output and greater overall intensity is required when simulating the environment just outside of the earth’s atmosphere (AM0) rather than simulating the environment present outdoors, on the ground, and at mid-latitudes (AM1.5G).  

Terrestrial or Space Solar Simulator: Depending on the specific conditions the solar simulator is intended to simulate, different spectral conditions will need to be adhered to. For example, greater UV output and greater overall intensity is required when simulating the environment just outside of the earth’s atmosphere (space solar simulator or AM0) rather than simulating the environment present outdoors, on the ground, and at mid-latitudes (terrestrial solar simulator or AM1.5G). AM1.5D and AM1.0D are less common air masses used in terrestrial solar simulators.

The Solar Constant and Solar Simulation


The radiation from the Sun is measured in two ways for a variety of fields of research. The solar constant is the irradiance or intensity of light incident at the surface of the Earth’s atmosphere on a plane normal to the angle of incidence.


This value has been defined by the World Meteorological Organization to be 1366.7W/m2 outside the atmosphere. The irradiance of the Sun at the Earth’s surface varies under different conditions due to absorption and scattering effects in the atmosphere, and so a number of other constants are important in regards to the irradiance of a solar simulator.



Below the atmosphere the radiation emitted from the Sun can be divided into two components: direct radiation that comes from the Sun itself, and scattered radiation coming from the rest of the sky, including a portion reflected back from the ground. Solar simulators are adjusted to imitate the spectral distribution of sunlight for a variety of environments; to do this the spectral distribution from the xenon arc lamp source is altered and refined using Air Mass (AM) filters.


When discussing filters, the direct radiation spectrum is imitated using a direct (D) filter, and the total including scattered sky and ground radiation is matched by using a global (G) filter that imitates both components together.

Sciencetech AM Filters


Sciencetech’s AM filters are designed to be used individually for standard conditions, although they can also be arranged in series to produce other spectral distributions. Many solar simulator systems used by our competition require filters to be used in series to achieve the same performance as Sciencetech’s filters, for example using AM0 and AM1.0 filters in series to achieve a AM1.0 spectral distribution, whereas Sciencetech’s AM1.0 filter can be used alone to achieve the same result, reducing power loss and the cost of additional filters.

Sciencetech AM Filters
Sciencetech Xenon Arc Lamp Light Source

Most Sciencetech solar simulators use xenon arc lamps, which enables the system to produce an intense, collimated beam of light, similar to that of a 5,800oK blackbody. The biggest difference between the two is the xenon lines are present in the arc spectrum, and atmospheric absorptions in solar spectra, which is especially highlighted in the 800-1100nm range because of the intense line output of the lamp. An AM0 filter can reduce this effect so that the average level in specified bands matches solar levels above the atmosphere to better than ±25%, although complete elimination of the xenon lines while preserving the rest of the spectrum is impossible with a practical filter. AM1.0, 1.5 and 2.0 filters further modify the visible and UV portions of the spectrum for different sea-level conditions, and coupled with the use of high pressure Xenon arc lamps Sciencetech is capable of producing Class A standards for our solar simulators.

The graphs on the right show the typical output spectra of Sciencetech’s fully reflective solar simulators. These spectral irradiance curves combine the spectral curves of the xenon arc lamp source, air mass filter, and mirrors used inside the solar simulator beam homogenizer. Actual output spectra may vary due to the condition of the lamp and manufacturing tolerances of the air mass filters. In order to simplify visual comparison of the spectral curves of our solar simulators with ASTM E927-10 standard curves, the simulator outputs are normalized to the corresponding standard spectrum.

Every time the illumination target size of a Fully Reflective Solar Simulator changes, the reflective mirrors inside the solar simulator that direct the light from the source to the target need to be refocused. Although this can be performed manually, the procedure is a hassle should the user need to change the target spot size frequently. The solar simulator would need to be shut down and have each internal mirror re-adjusted to support a different focal spot size. With this variable focus option re-adjusting the internal mirrors of the solar simulator is performed through a single knob without having to shutdown the solar simulator. This feature can also be used to vary illumination intensity by spreading the light over a larger area or concentrating the light into a smaller area.

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)

With the Sciencetech Solar LightLine you can direct the Class AAA solar light anywhere you want. Classic designs for solar simulators require you to bring your sample to the solar simulator. Now, you can bring the solar simulator to your sample! This makes the Sciencetech Solar LightLine series of fiberized solar simulators ideal for research that just can't accommodate traditional bulky solar simulators. The solar light can be easily integrated with a glove box without mounting the entire solar simulator in the glove box, saving space and adding flexibility. The standard 4-foot-long fiber makes the simulator ideal for doing spot checks of devices on manufacturing lines or in dedicated setups that can't accommodate a bulky solar simulator.

The Lightline includes space for fitting one internal accessory. Options are a motorized, 6-position filter wheel, with a variety of spectral or neutral density filters that can be supplied. Or a manual or motorized attenuation system that provides continuous control over intensity at the target from 10-100%. Internal accessories must be selected at the time of order and cannot be added at a later time.

Every Lightline includes an internal two-position filter tray that accommodates Sciencetech FT style filters. Model AX-100 and AX-200 come with a removeable FT-style filter that permits one sun operation. One filter location is reserved for the selected air mass filter. Air mass filters must be selected in the order for spectral match classification.

Classification is performed to ASTM E927-19. Classification to IEC 60904-9 and JIS C 08912 standards can be performed on request. Please contact your Sciencetech Technical Representative for details.

- Includes adjustable touchscreen 601-series power supply with current control from 80-100% of max current.
