With this project we've pushed the limits on what we have designed and manufactured at Sciencetech. It was a great experience to work with the various team members and we are excited for similar projects in the future.

Sciencetech, a leading innovator in solar simulation technology, has completed its largest high flux solar simulator project to date. Working with a university located in France, the expert team at Sciencetech designed and manufactured a seven lamp high flux solar simulator. In mid-September 2024 two team members were on site in France in install this equipment.
This newest high flux solar simulator design was inspired by the work done by Xian Le, et. al in their paper A 28 kWe multi-source high flux solar simulator: Design, characterization, and modeling. Improving on previous scientific work, Sciencetech's design includes a frame to suspend the lamps vertically, a stage for accurate sample placement, and a housing to safely encompass the high flux solar simulator. Continue reading for more details about this milestone system.
Each of the seven 6.5kW lamps is self contained in it's own unit suspended from the overall frame. This allows for individual control and adjustment of each lamp along the optical axis (+/-5cm) and a housing rotation and tilt adjustment of (+/-30) degrees. The igniter, reflector, and all electronics is mounted with the xenon lamp and any cables and hoses are safely attached to the frame to avoid any hazards from having them adjacent to the working area of the unit.
An XYZ stage is included with the system for positioning the solar furnace or sample that allows for displacement as small as 10cm and can support samples up to 30kg in weight and up to 80cm cubed in size. The measurement system is able to measure the spatial irradiance of a 20cm x 20cm target. This is performed in two ways:
XYZ movements of a calibrated Gardon gauge measuring each point as it travels the specified target area.
An industrial camera calibrated to measure the intense light reflected off a custom water cooled, alumina coated Lambertian plate. The benefit of this is the ability of lamp alignment in real time knowing the exact power distribution that the final device under test will be subjected to.
For the safety and protection of the user the high flux solar simulator is housed within a larger unit. Consisting of aluminum panels and a roll down door, the scientist conducting experiments can view the solar simulator through a tempered glass window with protective curtain located on one side of the housing. Also included for safely is a warning light located near the door, showing with the system is operational, and vents along the top and bottom to allow for adequate air flow for the system. This housing allows for optimal operation while maintaining the highest safety standards.
