AM0 Solar Simulators

Introduction

Most of our solar simulators can simulate the AM0 wavelength distribution by changing the AM filter. However, an AM0 solar simulator that provides the solar constant (1361W/m²) and spectrum matching up to 1800nm requires a lamp with higher power than an AM1.5 type solar simulator.

The following models are designed for space development or for testing multi-junction solar cells. In particular, the AM0 compatible models of the RHS series have a high level of spectral matching over a wide range up to 1800nm (1900nm). This makes the measurement procedure simpler, especially when the reference cells and test cells have different spectral responses.

The irradiation area that can be supported currently ranges from 50mm x 50mm to 300mm x 300mm, but we also support other sizes by special order, so please feel free to contact us.

Product Series

• RXS series: Standard models with single Xenon lamp.
• RHS series: High-end models which optimized for AM0 spectrum distribution.
• RMH series: Large-scale products for measuring solar modules, with an irradiation area of 1m x 1m or more. It utilizes a system with metal halide (multi-lamp type).
• HC series: Highly collimated solar simulators boasts a collimation angle close to natural sunlight, making it ideal for measurement of sensors such as Sun Sensor that require parallelism of incident light.

RHS series: High-end models optimized for AM0 spectrum distribution

Model: RHS-220SS

Model: RHS-100SS

The high spectral match solar simulators (RHS series) employs dual lamp system consisting of a xenon lamp and a halogen lamp. Because the infrared spike from xenon lamp is eliminated, this special design creates an optical system that can provide more natural and optimized artificial light than solar simulators only using xenon lamp.

HC Series: Highly collimated continuous solar simulators

Model: RXS-200D-HC2

Model: RXS-150D-HC

The main purpose of this product is simulating the energy intensity and collimation angle of direct sunlight, taking into account the irradiance stability/uniformity and having a irradiation area >φ150mm.

The design feature of this product is the use of a coaxial transmission collimating optical system, which can achieve a high collimation and simulate a solar constant under the condition of AM1.5G or AM0.

The collimating optics of this product consists of an optical collimation objective and a field diaphragm. By ensuring that the light intensity in the effective irradiance surface reaches the standard solar effective irradiance surface reaches the standard solar constant, the optimal aperture of the field diaphragm is designed to achieve or even better than the collimation of the direct sunlight collimation angle (within a half angle of 0.3 degree).

Applications

• Measurement of sensors such as Sun Sensor that require parallelism of incident light.
• Concentrating solar cells (CPV) performance evaluation.
• Hot spot test / Burning lens test: This test evaluates the performance of automobile headlights and head-up displays (HUDs) under high-intensity light sources.
• Test of visual artifacts: This test assesses the quality and clarity of in-vehicle cameras and monitors under different lighting conditions.
