OTENTO-SUN II Solar Simulator

Irradiation of pseudo sun

The Model OTENTO-SUN II Solar Simulator employing the Xenon lamp and AM1.5G filter irradiates pseudo solar light on the sample such as a solar cell to evaluate its characteristics. The Model OTENTO-SUN Ⅱ conforms to the Japanese Industrial Standard (JIS ) and is ranked into Class AAA which is the best according to the classifications of grades in JIS.

Optional filters are set on the Model OTENTO-SUN Ⅱ, which can beused for the following purpose.

  • Linearity of the light intensity of the sample when using the ND filter
  • Irradiation of monochromatic light by the color filter

This model is superior in stability of light intensity with the feedback system monitoring it in a real time employing a constant irradiation power supply.
