Optimize Schlieren Projects with Chronos High-Speed Cameras
Chronos highspeed camera systems offer the portability, ease-of-use, and video quality required by Universities and R&D Labs to understand Schlieren Imaging in-depth.
What is Schlieren Imaging?
Schlieren Imaging is a technique that allows us to see the subtle changes in the refractive index of fluids. It can reveal the flow of air, temperature variations, and shockwaves that are otherwise invisible to the naked eye.
How does Schlieren Imaging benefit from Chronos High Speed Cameras?
High-speed cameras coupled with a Schlieren visualization setup can capture rapid changes in air density or temperature that are not visible by the naked eye. With Chronos High-Speed Cameras, unlock the intricacies of Schlieren Imaging processes and get ready for detailed analysis and visualizations, all with unparalleled efficiency.

How does Schlieren Imaging work?
In a uniform medium, light travels without deviation. However, when the medium is disrupted by changes in pressure or temperature, its density fluctuates, altering its refractive index. As a result, a beam of light passing through this changing density can no longer follow a straight path; it bends and twists. Enter the “knife-edge,” a thin, rigid object strategically placed in the light’s path. It filters out the unaffected rays, allowing only those bent by the changing medium density to create the captivating images you’ll see on your screen.
