Highly Collimated Series
Precision Solar Simulation
Providing the collimated Solar Light: Custom-Engineered for Specialized Performance
Model: RXS-200S-HC2
The main purpose of this product is simulating the energy intensity and collimation angle of direct sunlight, considering the irradiance stability/uniformity, and having a large irradiation area (φ150mm/φ200mm).
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 AM1.5D or AM1.5G (1000 W/ m2, according to the energy distribution in the range of 400nm-1100nm).
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 irradiance of AM1.5G, 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).
In addition, by switching the field of view diaphragm with different apertures, the requirements of illuminance test and luminance test can be respectively corresponded to.
*Collimation angle
Regarding the evaluation of parallelism of light, we use the concept of CHA (Collimation Half Angle). → Learn more about Collimation Angle
Applications
- 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.
- Concentrating solar cells (CPV) performance evaluation.
- Measurement of sensors such as Sun Sensor that require parallelism of incident light.
*Burning glass / Burning lens
A burning glass or burning lens is a large convex lens that can concentrate the sun's rays onto a small area, heating up the area and thus resulting in ignition of the exposed surface. Burning mirrors achieve a similar effect by using reflecting surfaces to focus the light. They were used in 18th-century chemical studies for burning materials in closed glass vessels where the products of combustion could be trapped for analysis. The burning glass was a useful contrivance in the days before electrical ignition was easily achieved. (From Wikipedia)
