Ideation and designing the system
An ellipsoidal back reflector collected a significant portion of the lamp emission and focuses into a homogenizing light pipe. This light pipe guides the light via total internal reflection and the many reflections serve to mix the light rays, making the output more uniform. An array of lenses and turning mirrors were used to direct the light to a collimating mirror which reflects the light to form nearly parallel rays, producing high irradiance and low beam divergence at the target plane.
Mechanical Design for Automated Motion Control
Our customer required automated motion of the entire solar simulator in 5 axes—X, Y, and Z, as well as 2 axes of rotation. Additionally, the entire system needed to operate inside a cleanroom, necessitating isolation of the solar simulator’s air cooling system.
Sciencetech designed an automated mechanical stage and custom software to meet these automation goals, and provided a special cooling design, instrument components, and housing design to meet these needs.
The motorized movement system was built and tested and its software was created in-house. The movement system, housing, software, and optical elements were completed according to the customer’s specifications for all 5 axes of movement and a software GUI was included for easy control.
